Why can't I update my clash royale

Hi

Follow the instructions here, including checking that your address details fully match those on file with your card issuer / bank:

• Change or remove your Apple ID payment information - Apple Support
• Payment methods you can use in the iTunes Store, App Store, and iBooks Store - Apple Support

You may also wish to check with your bank (in case it declined Apple's payment authorisation request).

If you still need help, contact iTunes Support:

Contact - Official Apple Support

SSomething is def. going on with Apple and their verification process. I have tried 3 different cards to be told the same thing you are. None of my games are updating and I can't download free games.
