Won't work – Star Wars Card Trader by Topps Review

Had trouble with my iPhone 6s and had to take it in to the phone tech. He couldn't get it to work without having to reset it to factory settings. Now I can't sign in and have contacted app support. I followed their directions and still can't sign in. I didn't have this problem with the Panini card apps.
