Wondering if anyone else is having this same issue. Basically I go to my home page in the app and its full of offer from sellers on things I haven't even looked at and an item it said I purchased which I didn't, and isn't even on my purchases page. I can't change my password due to an error message, I can't log in through another device because 2 step verification isn't working and I can't switch 2 step off either. Ebay answer via twitter was to just create a new account, which I obviously don't want to do as this account has my seller feedback.
