Ditto to the last commenter

Im in the same boat, I am pretty sure that I signed in with my Twitter account and now I have absolutely no way to sign in anywhere to handle disputes or contact customer care etc
In the app I can purchase and message sellers etc.
Im beyond annoyed wasting my danm* time trying to simply sign in...?!?
