Studio login problems

Studio has been working ok’ish (I’ve noted other problems previously)

Tried to login today (day 7 of 30 day trial) and it’s just stuck at the login screen.

…Little dots run under the password when I press “Login” - bit there it stays.

~I did wonder if there was a password problem (it’s stored in a password manager, so I don’t forget) but tried “forgotten password” and the next screen comes up with “bad request”
