Yes, I did have this problem. It even triggered a fraud alert for my card. Eventually, on the 4th try it went through (without that pesky secondary verification thingy). In my case, the first error was because I used my parent's card and they did not respond with the verification code. This 'locked' my payment portal so that I had to call the app service. I called and emailed with no answer. Got fed up and reloaded the app and to my surprise, I could enter payment info again. Used my card. Got an error. Did it again and error but this time a fraud alert. Cleared that up and then tried again and it worked. PERSISTENCE IS KEY.
