Bubble authenticator sends message “login session has expired / changed.”. 1000s of users are affected. Bubble support creates a ticket and has no solution.
Please dont use bubble if you want to develop a serious app.
I have been using the Authenticator app to login to Bubble and it hasn’t caused any issues for me yet. 
Never experienced any authentitcator issues or heard of it happening. Are you sure everything is set up right and nothing has expired?
What I HAVE experienced is the futility of bubble support. I Never bother with them. Response is never timely, usually useless, and often they send you on a wild goose chase trying to reproduce it only to have someone, who is in way over their head, finally claim its expected behavior.
