The thing is, I am using a third party library for those dialogs. They would be very interested in a minimum reproduction of the problem. So I wouldn't have to invest to much time to fix it.
It is not related from upgrading from 0.48 to 0.49. (Very minor update that didn't touch anything related)
Basically it is doing "checks" (instance online, JWT works, banned, etc) Looks like it got somehow stuck each time on a check.
Which account(s) is this happening to?
It should have stayed roughly the same, that is also a separate bug. That I'll file
