I can confirm the problem - I've tried for a long time to get this to work, but to no avail - I've used both Firefox and Brave browsers, and Client ID from both Android and Windows.
So if it works for you @jonas, it would be great to know what OS and browser you're using - and where did you get your ID from?
Something you do must be different from what we do 
@jonas Sorry for bumping an old thread, but what @fito said is true.
I just tried to register with Zanata, and got this message:
Maintenance-only Zanata Instance
This service is in maintenance mode and new projects are not accepted, sorry.
Since the upstream Zanata project has been unmaintained for quite some time, we have decided to continue supporting existing projects as much as possible but refuse new projects. Adding new language coordinators is also not possible, although if you've been around for some time we might add you as reviewer to ease the situation.
Another translation service is Transifex.
This may be a horrendous suggestion, but wouldn't it be kind of fun to have a translation toggle for the lyrics?
I listen to songs in lots of different languages; the world is full of fantastic music
Even if an automatic translation surely will mangle the lyrics, it will reveal some semblance of what the song is all about (and it's what I have to do anyway, by means of copy & paste, if I want to understand anything).
Hi, all!
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.
