please fix!!

ever since the update I tried to make an order but when I clicked place order I get a pop up that says my credit card failed. I thought I had a problem with my card so I called my bank and they said everything was fine I even bought something from a different app and it worked so it definitely wasnt my card. I went to forever 21 on my laptop and made my order there and it worked so there is something wrong with the app if I wanna make orders I dont wanna pop that says my credit card failed when I know it didnt please fix!
