Tidal favourites, playlists have disappeared

Roon is no longer synching properly with my Tidal library. All current tracks, playlists, albums, etc. in my Tidal account have mysteriously disappeared in Roon although I can still access them via the Tidal app directly. I also still have access to Tidal via the Roon app but all the playlists, etc. are gone. I’ve never had any issues with Tidal integration in the past. Any ideas how to fix?
