Tidal acting weird

Within the tidal app (iOS) all is fine.

When I try to access Tidal via LMS I get for example for my favourites the result “This search does not deliver a result”.
I can load a list like pop and start a title but it won’t play saying “The user does not have a valid session” and nothing is played.
So I have some connection to Tidal to be able to load song lists but it won’t play music.
Anyone here with the same experience?

It happened on 8.1.1 an now also on latest 8.2. Nightly.

Thanks!
