In attempting to add my first Payment (a VISA card) in Wallet, I'm not able to enter my address in the Billing Address field.
Problem solved: I had to first add an Identity Safe address (me). Once that was done I was able to edit my VISA Payment card by selecting my name from a drop-down list.
Thanks rch847 for letting us know you got it sorted - it just might assist someone else with a simialr problem.
