I've had a few issues logging in recently:
1. I tried to log in from Firefox on Android but the login screen never appeared, just the three "loading" dots
2. I tried to log in from Firefox on Windows via a reply link in an email and after putting in my username and password the login button didn't do anything
3. I tried to log in through the normal login page (not reply-to login) and the login button worked but sent me to an address that was for an app on Android, I assume the Nokia Phones support app. I then backtracked and found I was actually logged in so came here to report these issues.
Thanks for reporting madbilly! We'll look into these.
Have a wonderful Monday!
