Can’t Link Apple Music Account to Stats.fm (The login process was unable to be completed)

Hello everyone,
Since Spotify keeps getting more expensive, I’ve decided to switch to Apple Music.
However, when I tried linking my Apple Music account to statsfm, I ran into this error:

Has anyone else experienced this, and do you know how to solve it? (if there's a way, it looks like Apple Music is completely broken on statsfm...)

Thanks in advance!
