This is what I encountered. This list is a playlist of MP3 files Top 100 of 2001. As it is a collection and self ripped they have no album tag 
And yes, I tried with some other playlists and they could be optimized.
In my eyes a bit a weak implementation as it don’t grab titles from Quobuz even if artist and track name is in the metadata of the MP3s 
Thanks’ for your comment.
Best DrCWO
I still don’t have this upgrade :(.
The Playlist Improver is available in Roon only on desktop and tablet platforms.
I just wanted to say thanks for inspiring me to do something about this playlist of mine.
It is a collection of tracks in really mediocre .mp3-quality, the Swedish Top40-list you could call it. It is based on the sales of singles in Sweden from 1984 until 2006 when the radio show was cancelled, due to change of nature in sales.
The radio show that presented these pop songs was called Tracks, and we were many many who recorded these shows on our casette decks.
Anyways, i have had this collection of songs for many years, and considered replacing them with tracks from streaming services and my local tracks. The collection playlist is almost 4.000 songs and is very well organized.
Roon treats this collection as an album, based on my tagging “Album title: Trackslistan 84-06”. So i just took this album, created a playlist from it’s contents.
Now, i am going through this and replacing tracks individually, but it is VERY cumbersome in Roon.
What is missing is a rudimentary check against local and streaming service libraries:
Do i have a track match using Artist and Title (preferably also release year)?
What it looks like right now, is i click the artist “Howard Jones” in the playlist, and get redirected to some dude who most people never heard of?
Same thing if i click Phil Collins:
And what makes this a total chore, is that Roon is sooo slow when doing this, it takes a few seconds between each click on an artist, till i can decide wheteher the artist is correct or initate a search, (where of course both Phil Collins and Howard Jones as hit makers comes first, pretty quickly also)
It seems also that if there are more than one likely artist-hit, it does NOT match with the one that is already in my library or most frequently searched or whatever priorities. Oh, maybe it picks up on the first name match, where they are present in my lib but from unidentified albums? 
The process is very tedious though, and it IS bringing my Core to it’s knees after a hundred songs or so, making it slower and slower. ( remedy ~ restart Roon Core)
So, @Roon please, please consider a smarter identification process, preferably a batch job: “Go match these, and give the results back with options to abort, create playlist, review what was not found etc…”
When searching on basic tags like artist and track identification is pretty exact, but the software makes it complex and high friction…
+1 from me 
I get that. However, on my laptop and iPad I do not have the option to improve any playlist.
Good morning,
Congratulations to the team of Roon for developing this new tool to improve the Playlists.
My Roon Core is on my MacBook Air M2. Unfortunately the Improver button is not visible at the bottom of my Playlist.
Thank you for following up on this post.
Wow! Just added my entire (small) library to a new playlist. Improved the entire catalogue by removing duplicates and upgrading quality. Saved changes to the library then deleted the playlist. Job done! Thanks Roonie Team. BTW didn’t initially realise this feature is currently limited to desktop and tablet. Not a biggie.
I wonder why this feature seems to work for some, and not others. Strange.
No idea unless there’s nothing to improve!
Also note this function is not currently available on your phone.
The improver is improving tracks on playlist. It doesn’t change out album versions if that is what you expected. Hopefully in the future!!
So I’m looking through these issues and mine (along with someone else who has the same issue) that is Roon doesn’t see ‘unavailable’ albums in Qobuz, doesn’t seem to get a mention much? Has this been noted or moved to another thread? Because really this is the only thing about the improver that is really needed… missing albums and tracks are a nightmare with Qobuz!
This issue was raised by several users (including me) in Early Access. It’s under investigation by Roon Labs.
Ah excellent, thanks 
The Playlist improver is generally working well, but I do have one recurrent problem I wanted to report. I’m mainly using it to improve Tidal playlists that change daily (my own playlists, not Tidal created ones). Most of the time, after using the improver tool the first time on a playlist, the updates don’t stick. Often I try again, same result. However, if I go in and manually force Tidal to sync in Settings, then return to the playlist, use the improver again, then the changes stay. This is pretty consistent daily behavior I’m seeing, although once in a while the changes will stick after the first try.
I have just discovered Playlist Improver. It is FANTASTIC! Thank you so much Roon. Identifying the tracks that have disappeared from Qobuz is just so helpful, as are the other elements. Good work!
Is it possible (or could it be possible) to counfigure a playlist to automatically improve? i.e. as new tracks are added in future to a playlist, quality is automatically upgraded. I have scripts that create playlists for me daily that would be great to have them automatically upgrade the quality of the tracks.
I really like this feature.
Would it be possible to modify the ‘Match to Library’ function so that it selects the correct version? For example I have 192kHz 24bit songs in my playlist for the car and want to downgrade them to the 44.1kHz 16bit versions in a single click via this feature. The benefit is that in doing so it will use the downloaded files from my Roon server instead of tearing the backside out of my mobile data plan (ie using Roon Arc and the linked steaming subscription service). Given I live in a semi-remote location the mobile data reception is spotty throughout parts of my car journeys. The 44.1kHz 16bit version in this example is already set as the Primary Version of this album.
Doesnt work for me at all with tidal playlists, improvements just reset back within 10 seconds
I appreciate the effort here as playlist management outside of the basics in Roon imho is lacking. Improving quality and so on is great but it still seems unable to fix/find orphaned entries. Those that don’t say unavailable but are essentially dead links - no thumbnail but it still shows valid front-end tags like Composers, Album etc. and when you try to play it just zips through saying the Track is no longer available on Tidal. Clicking the Album similarly fails but you can click the composer, go to Discography and choose the album again from there. I’m presuming the publisher removed and re-added the album leading to different guids and so on but to me this is something the improver should also be able to check for, it seems to happen reasonably often (at least for me).
