884 Roon - Tidal synchronization problem after update

After the 884 update, I have a problem with Tidal synchronization. The playlist that was updated and synced every day has shrunk in Roonie from 429 songs to 310. In Tidal it’s still 429. Trying to sync to nothing. Resetting everything possible also doesn’t help. Anyone have a similar problem or know a way to solve the problem? Roon Server on Qnap 453BE, dCS Bartok.

In amongst resetting everything, have you tried logging out of all instances of Tidal, removing the Tidal service from Roon, adding it back again and then logging in once more?
