I have attempted to change my password on Firefox, Chrome and Edge on Windows and Safari and Firefox on IOS. All I get is a spinning circle and no change in my PW. Not sure if anyone else has encountered this issue. I sue upper lower case, numbers and special characters of varying lengths to no avail. Not sure if anyone else has encountered this issue.
I can’t login on any of my mobile devices. Does same thing as yours, get a spinning circle. Kept me from signing up as well. Ended up using a desktop pc to sign up and it works fine there. If you have a PC give that a shot.
