trying to update apps but invalid address keeps popping up
Recently every time I try to purchase apps or update apps on my iPad a badge pops up saying "Invalid Address tap continue to sign in" I hit continue and my address is correct, but my credit card 3 digit code is missing. I enter that and tap done I then try to update again and the same invalid address badge pops up again. This problem just started this week and it's very frustrating. I tried changing my password and now I'm having the same issue on my iPhone 4. Has anyone seen this or have any advice? Thanks
