It is NOT working for me. I uninstalled, reinstalled. Everytime I select to login to Apple, a blank popup shows up. If I close it, another automatically reopens. But it never brings me to a login page. It was just working a few days ago, I don't know why I even got signed out.
Edit: I'm on Windows 11
Edit 2: I followed the intructions on Twitter from another thread, and it resolved the issue.
