Cannot setup Apple Pay

1. Sometimes if you sign out of your Apple ID and back in it resolves the problem.
2. Check your Apple ID region to make sure it is correct. If it is correct, you may need to select the same region again. (Change your Apple ID country or region - Apple Support)
3. Check the region on your device to ensure it is correct (Settings>general>language & region - set to your region)
4. A passcode is required to use the Wallet app.
