Unable to Load a specific Libraries Recommended Page on iOS/AppleTV

I “upgraded” my RAM today from 64GiBs @ 3200MHz to 256GiBs @ 2400MHz not sure if this plays a roll or is even related to my issue, but for context I have added it.
My issue is that for some reason All home Users (and maybe even remote users?) and including the admin account user, cannot access a specific Libraries “Recommended” Section on any iOS or Apple TV device I’ve tried (Apple TV4k newest model, iPad Pro 4th Gen, iPhone 14 Pro). The Library recommended section of the library “Animated TV Shows” seems to be the only issue I’ve seen, and they can access that Libraries, Library Collections, Playlists and Categories. Just not the recommended folder. I’ve tried waiting multiple times for it to load but it does not and then eventually displays the Retry Connection screen.

Oh here is the Debug Log:

I previously fixed this issue by just restoring to a previous older snapshot, but now its happening again, but this time with a different library section. And I really Want to avoid having to restore to a previous snapshot again, if anyone has any ideas? @ChuckPa

This Began shortly after doing the following:
1 - Adding Multiple new Collections to multiple different Libraries. Many of the Collections were named the same name (IE Toonami & Jetix etc.) in multiple different libraries.
2 - Generated Tuners based on the Collections I made. And Started a connection to it via Plex Media Server.
3 - Ran Optimize Database via Settings > Troubleshooting > Optimize Database
4 - Restarted Plex Media Serrver and could no longer access one of the Libraries (this time Animated TV Shows)
5 - I thought Maybe its because Collections in TV Shows might not be able to have ‘&’ in the Collection Names for TV Shows, so changed all the collection Names that had ‘&’ in them even if they were not in the effected Library.
6 - Looked in the Console logs in Settings > Console and started seeing stuff like the following:


or

7 - So I thought maybe it has something to do with being unable to retrieve the Subtitles for either the Shows from my library that would normally be populated in the Recommended page for the Library or from the shows from the tuner. And I Changed the settings for some users in Settings > Account > AUDIO & SUBTITLE SETTINGS and deselected Automatically select audio and subtitle tracks and saved the changes. But Did not seem to make any difference.
8 - Also noticed that when starting the docker container I see Critical: libusb_init failed but the PMS still starts up in docker.

Things I’ve tried afterwards (to try and fix):
1 - ran DBRepair.sh script to try and fix any database issues (AUTO mode)
2 - Used DBRepair.sh script to try and purge any temporary files (there was nothing for it to do)
3 - Ran steps to clear DVR tuner settings (according to from Clear all DVR settings and start again Windows Plex Server since I thought it could have something to do with it?)

Attached is the Plex Logs:

Hi @michael_766 - did you find a resolution to this issue you were having from a few months back? The symptoms you describe - the “Recommended” screen problems and the Unknown metadata type: folder errors - seem similar to the problem that I’m having in my support thread (All iOS devices unable to load a subset of TV shows).

The solution I came up with was removing a bunch of collections within the associated Library, along with other Libraries. It seems when there are Library items that are also part of multiple collections, especially when the name of a collection is used in multiple different Libraries. And since Plex will group Movies or TV Shows with the same Collection Name together and display all items from any library that has the associated Collection Name. This was slowing down the loading of the Recommended for each associated library that had multiple collections that spanned multiple libraries in association, and/or had too many associations in the collections. And Some Libraries are slowed down so much, I believe Plex just gives up trying to load the page at all, because it takes too long.

Thanks for the idea + details!

Unfortunately the library I’m having trouble with doesn’t use collections at all, so I don’t think that’s the root cause of my issue. :confused:

Glad you were able to resolve your problem though! :smiley:
