· I currently am running the latest versions of ARC and Roon for iOS and macOS. my roon server is a nucleus one. Haven’t had any issues with it until recently.
Any metadata changes I make to an album will reflect intially in the ARC app, however after a few days, whether that be an album cover, tracklist change, or bonus track addition, it will revert back to the way it was before the edit unless I rescan the album in the roon app, which obviously is only available on my home network. This happens for about 30 different albums in my library and oftentimes if I don’t rescan those albums before I leave the house, I can’t play them as intended because they revert back to the way they were before any metadata changes were applied.
Is there anything I can do to solve this? It was happening daily when I was using a NAS as my roon server, but I purchased a nucleus and it stopped until a couple weeks ago, where it happens at least once a week. Unfortunately now i have to rescan my albums right before I leave the house every time now which is a pain.

Thanks for the report. Just to clarify here, you are making the change at home, using the (full) Roon app, and then you notice the change appear in ARC, and then it reverts after a few days? Can you please provide any example albums that display this behavior, along with any screenshots and timestamps you can share? Thank you.
Yes, I have updated all metadata via the roon app on my macbook. The metadata is fine in the roon app and never reverts. However, after a few days, or sometimes overnight (i’m unsure of the frequency) my ARC app reverts the metadata changes to what they looked like pre-edit. Here’s a few examples.
This particular album is a mixture of a Tidal album, an internal library track, and a merge of a single. In roon it displays the album perfectly. This is what it looked like last night:
and then this morning when I was at work I noticed it had reverted. note that the correct title still shows when i scroll, and that I was able to play other songs from the album from a playlist (which is showing on now playing) but the album page looked like this:
I can only get it to show the correct metadata changes when I go into the roon app on my computer and rescan each album. Then it shows correctly again. So something in ARC is not keeping the changes.
Thanks for the extra screenshots, these are really useful, and they actually pin down what’s going on.
First, we can rule out the NAS: your library files all seem to be on the Nucleus One’s internal storage now.
The key detail your screenshots show is that this isn’t ARC losing your metadata, it’s the version being displayed that’s changing. Each of these albums (Access All Areas, SO CLOSE TO WHAT???, GUTS, etc.) is a grouped set of multiple versions, with your edited multi-source version set as the one to show. When an album reverts, the title stays correct (which is why you still see the right name when you scroll), but the “Currently viewing” version has quietly switched to a different member of the group, for example, Access All Areas dropping to the single-track “Fly Girl,” and SO CLOSE TO WHAT??? flipping from your 20-track version to a 15-track one with a different cover and tracklist.
Your server logs line up with this. Roon re-checks album identity after the server restarts and during an automatic metadata refresh that runs overnight (around 1am your time). On these grouped/composite albums the identification is intermittently failing, I can see it happening on Short n’ Sweet, where it came through split into two pieces that both returned “could not identify.” When that happens, Roon falls back to a different version in the group, which is the revert you’re seeing. A rescan re-runs identification and re-applies your chosen version, which is why it fixes it every time.
A couple of the failures also coincided with the Nucleus briefly not reaching our metadata servers, which explains why it’s intermittent rather than every night.
Two things that would help me confirm and move this forward:
Next time you catch one reverted, note the date/time (your local time) so I can match it to the exact refresh or restart in your logs.
If possible, make sure the Nucleus has a stable, uninterrupted internet connection overnight, anything dropping its connection during that ~1am window could be contributing.
Could you temporarily connect your Nucleus directly to your primary router?
We’re having our QA team attempt to reproduce this in the meantime. Thank you!
Thank you for your help! This all sounds correct as to what’s happening.
I did a rescan last night when I returned home from work. This morning, I did catch that Access All Areas was reverted 11:54am PST. The others appear fine at the moment.
I’m at work now but will connect the nucleus to my modem when I get home this evening.
Alright, nucleus has been connected directly to the modem as of 11:55pm PST. Rescanning tonight and will report back with anything that changes in the AM.
Thanks for the update @Evan_Adams, if you do see the same issues revert, take note of the general date and time and we’ll see about taking a closer look.
My server just crashed. Its 11:05pm PST on July 25. The roon app on my computer went into a “looking for roon server” loop. ARC would not load. I restarted the nucleus. Several of my albums reverted on ARC in the process. They had been fine since I connected it to the modem 3 days ago.
Sorry you hit this, thanks for the exact time, that made it easy to pin down from fresh Roon Server logs.
Good news first: your server didn’t actually crash. There’s no error, no out-of-memory, nothing like that in the logs, the RoonServer process was healthy on memory right up to the end. What happened is it got progressively bogged down until it stopped responding, which is why the app landed in the “looking for Roon server” loop and ARC wouldn’t connect. Rebooting the Nucleus (which you did) was the right call to clear it.
Here’s the sequence I can see. Right around 10:54pm your time, a remote connection started rapidly connecting and dropping over and over, reconnecting every couple of seconds and repeatedly failing mid-handshake. At the same time the Nucleus was having trouble reaching our cloud cleanly (timeouts and dropped SSL connections). Between the two, the server piled up more and more stalled connections until it couldn’t keep up with normal requests, including talking to its own audio service. That’s the unresponsiveness you experienced. Then on the restart, Roon re-ran identification while things were still settling, and several grouped albums fell back to a different version, the same revert behavior we talked about earlier.
The common thread is the network change. Since moving the Nucleus directly onto the modem, its remote/internet path looks unstable, we can see the remote-connectivity checks failing (502/504), and with no router in front there’s nothing handling port mapping, which lines up with that reconnect storm and ARC struggling.
A couple of things I’d suggest:
Put the Nucleus back behind a router rather than directly on the modem.
And as before, if you catch another revert, note the local date/time so I can match it to the exact moment in the logs.
Let’s get the network back to a stable setup and see if the freezes and reverts stop together.
Wanted to follow up on this. Were you able to keep an eye on things after the steps we mentioned and see whether the issue changed at all? If you ran into anything different, or if there is still more we should look at, just reply with the latest details and we can take it from there.
Please note, if we don’t hear back from you this thread may close automatically soon. If the thread auto-closes and you need further assistance, please submit a reopen support request via the technical support help form below and specify that the issue should be reopened. Thank you.
Just opened Roon ARC at my office and several of my albums have reverted. GUTS by Olivia Rodrigo, Access All Areas by FLO, Dopamine by Normani, Future Nostalgia by Dua Lipa are a few that i’m noticing immediately.
However, other albums that usually revert like SO CLOSE TO WHAT?? by Tate McRae, Something Beautiful by Miley Cyrus, and MAYHEM by Lady Gaga are currently displaying correctly.
I noticed this around 11 AM PST. Last night before I went to sleep, around 10PM PST, I made the post above this one, where everything was fine. So it occured overnight or early this morning.
