ARC still can't survive WiFi --> Cell dead zone --> Cell working zone transitions

Even with the latest updates, ARC still exhibits the behaviors noted in:

An ARC reliability observation

I’ve been using ARC, largely successfully, since launch. As many of you know, I run Roon on my Synology NAS, where I also have Audio Station/DS Audio running alongside Roon as a secondary platform. My house is in a cell service shadow, and with DS Audio, I got into the habit of starting DS Audio on my phone on WiFi before leaving the house, so that I could be sure that I could get some music buffered and going from my driveway until I got cell signal again. This always worked well with DS Audi…

Roon ARC stops playback unexpectedly while switching from WiFi to cellular (ref#RQP7GE)

What’s happening? · I'm having trouble with Roon ARC What best describes your issue with ARC · Other Describe the issue Arc decides it has nothing to play. Yet album being played had not finished and remaining tracks still in play queue. This happens quite often and more apparent when moving from WiFi to cellular but not immediately can be after a good number of tracks. In this case album was started on cellular. If I go to queue and play the next track it will. But this isn’t the point. Des…

This is tiresome, really. I do not feel that Roon Support has engaged with me meaningfully to get this resolved, despite repeated attempts to offer whatever information I can. I’m incredibly disappointed, to say the least. Is someone willing to actually engage me regularly to help debug this and solve it, once and for all?

The below screenshot combo should never happen, don’t we all agree? Yet this is what happens once I get back on cellular after going from home wifi to cell dead zone back to cellular functioning…

Hey @DDPS,

Thanks for sharing an updated report on this issue! Investigation into improving this behavior has been ongoing with the team, and I apologize in that none of the updates so far have helped you.

Based on the screenshot you’ve provided, we should be able to take a closer look into your Arc diagnostics to see where improvements can be made.

Thanks for your continued patience in the meantime! I hope to have additional information to share soon, once the team has had time to review your case.

Thank you @benjamin - please let me know what I can do to provide extra detail that could be of help. I would not be bothered at all if the Roon team wanted to ask me to do specific things to help debug this.

Hi @DDPS,

Thanks for your help and long-standing patience. Development is actively investigating this case, so if you continue to reproduce it anytime you leave the WiFi network, please note the timestamps here.

This will help expedite the investigation since we won’t have to corroborate each log instance against other known examples to confirm it’s a relevant symptom.

[DDPS]

OK will do. Thank you so much @connor!

i can actually reproduce it when i’m on cell signal and have a drop in cell data it keeps showing poor connection until i restart the app. Don’t know it if its the same thing, but it feels like the same.

Hi @Edgar_Rodriguez,

Thank you for the report - are you able to provide an approximate timestamp of when this last occurred for us to attach to development’s investigation?

~7:45 AM EST, happened again for me this morning.
