I've been struggling with this issue for quite some time. The settings for Online Music Integration keep switching from enabled ('Integrate online library') to disabled ('Do not integrate').
The attached image is from a fresh install I spun up a few weeks ago to test to see if the issue was just my old installs that's been used for several years -updated as new releases have come out using the built-in updater.
Sure enough tonight I decided to listen to music and sure enough both Tidal & Deezer were disabled. This image attached shows Tidal as disabled, but I just re-enabled Deezer and did a rescan - then shook my head and decided to post this

This happens for ALL the online libraries - Spotify, Tidal, and Deezer.
Unfortunately I haven't been able to exactly pin down when they become disabled - next auto music rescan? after restart? some other event?
I run 3 different instances on some mini pc's and this happens on all of them.
