upmpdcli Tidal plugin

[GioF_71]

good morning,
with 9.1.0 I tried this starting with 3. (get credentials), first trying OAUTH2 (also with the alternative of editing upmpdcli.conf as instructed) and then PKCE. No error messages but login fails.
Are steps 1. and 2. necassary to get this to work with 9.1.0?

Hello, can you provide:

1) upmpdcli.conf
2) listing of /var/cache/upmpdcli/cache/tidal, especially .json files (don't post the contents, just the file names)
3) applications logs

Thank you
