I have an API token from the Tidal app on my Android phone, and a valid user account (I can stream both from the Android app and the Tidal web player), but using that token in the Strawberry settings for Tidal, along with my username and password, gives the error "Authentication failure: Client not found (401) (8003)".

I read that to say that the API token is valid only on my Android device?

Anyway, it seems to me that Tidal now only supports the OAuth token based API calls?

However, if I select "Use OAuth" in the Strawberry settings for Tidal, and my username for Client ID, then a Tidal login web page opens, stating that "Something went wrong. Please try again. If the error persists, contact customer support". The same happens if I try to use my Android API token as Client ID.

I haven't contacted Tidal customer support on this issue, because I did contact them to get an API token, and they were totally uncooperative

From https://github.com/strawberrymusicplayer/strawberry and the discussion comment at https://github.com/MusicPlayerDaemon/MPD/issues/545#issuecomment-506386102 I get the impression that Tidal should work with Strawberry, but I'm sadly stuck.

Am I doing something wrong, or is this feature no longer working?

Edit: I'm on Linux by the way, and please just ask if you need any details.
