The credit card expiration date field on my iPhone 11 Pro is corrupt.
It looks like this: M' YY, with a strange looking "apostrophe" character instead of a second "M." After entering the first character of the expiration month, the cursor skips straight over to the first "Y" character. Thus I cannot enter a payment method using a credit card.
It is NOT an iPhone 6 running iOS 12. It is an iPhone 11 Pro running iOS 16.5.1
