Can’t make payment: All contingencies have not been resolved.

Description

I am trying to make a payment to my friend, and it showed on the app that “ Our application is experiencing an issue. Please try it later. All contingencies have not been resolved.” I am not sure is it because I can’t confirm my linked card. I tried to link two cards. One debit card one credit card, but both showed “Looks like something went wrong on our end. Please try again in a minute or two.” At the top in red. I have tried it the next day but it still didn’t work. I still cannot confirm my cards. What should I do?
