I also had issues with my card! It wouldn't take my first card so I switched money around and used another card and I was lucky enough to get them. I was able to get row 30 on the floor, I think I'm next to or close to the B stage Slay me Queen.
Im so glad I got my tickets although I'm looking at my credit card bill and it says pending still which is scaring me but they accepted it so I don't think it means anything
that happen to me so many times today, especially i finish everything click submit and it tell to return back from the beginning
