I can't add any tickets, passes, etc., except credit cards and travel passes to Apple Wallet

Hi,

I have recently discovered that I am unable to add any tickets, memberships, etc., to my Apple Wallet and upon doing so I receive error messages like, "Sorry, this pass isn't available right now. Please try again later.". Additionally, on the Apple Wallet, when I press the plus in the top right, it only provides me with the options to add credit cards, or travel passes rather than anything else.

I have updated to the most recent IOS 16, and have restarted my phone, changed the region to a compatible one, and have found that the error still persists.

Any assistance would be greatly appreciated.
