Edit: didn’t see the comment about the email not working for eternity before I replied here, logged in now, thanks!
No 2fA enabled, and eternity just provides the error “Can’t fetch user data” after I provide my details Anywhere I might find a log to give more details? When I noticed the upgrade was finished I started getting communities back in my feed I had blocked so that triggered me to try re-logging in, but to no success
This has let me log in, thanks!
