HI @kanar , I’m not sure if it’s related (link to issue), but I was logged out multiple times today - I didn’t have the issue where it said I didn’t exist, but I did have to complete 2FA 2-3 times in a row even after just submitting it…
Have you been able to login since?
I would try an incognito browser (or clear cache) and see if you can regain access.
