For the longest time Axis card did not work on Redgirrafe for me. However, it has been working for many months now. I am using my Axis Magnus here. Earlier I was using Axis Vistara infinite when it did not work.
First, you have to enter the OTP and then they ask for CVV.
In case its not working, I recommend writing to Payzapp, update app and try on both android and ios if possible.
