If you changed your username while in studio then it forcefully logs you out when you try to publish changes so you lost all prior progress if you haven’t published before changing your username. Expected behavior would be to have the studio session remain open so you can login and actually publish it instead of wiping all progress made since changing your username.
I don’t know how often this happens, but I’m sure it’s pretty consistent. I just don’t want to spend 1k each time I want to test this bug.
I believe this happens on any studio place you’re editing without team create.
This bug probably started happening around the same time you were forced to login to publish updates.
