Cannot log in with Apple ID

[leonboe1]

The Apple ID login is currently not working for me. I'm trying to log in since Friday last week.

I tried different browsers, different devices, and toggling adblock, Private Relay and Advanced Data Protection on and off.

If advanced data protection is on for my Apple ID, I get an "Authentication Error" from CloudKit, see here:

If advanced data protection is off, I get redirected to the website but there is a loading spinner where the profile picture should be, and it never stops.

When creating my account, advanced data protection was off. Maybe this issue has something to do with it. Just a guess, because with ADP enabled there is the authentication error, and with ADP disabled the console says something about an empty response when fetching record:

Not sure what is going on here.
