Microsoft Forms Site doesn't load properly...gets stuck in a loop

[DavidC55]

After entering my login details, it partially loads the Forms (Forms Pro) page but then gets stuck in a loop and I never get to be able to use it. It was doing this a few days ago then was fixed but the issue has come back again.

@DavidC55 Same problem.

Only old Internet Explorer seems to help when I have this problem
