How to open .PKPASS files on my iPhone?

I have a similar problem with tickets sent to me in messenger. However it works fine for the same tickets sent by the same person or organization on my wife iPhone 13 running 17.4.1 which is identical to mine. When she receives a ticket via messenger it shows the actual ticket in messenger and functions as expected. When i get the very same ticket from the same sender on the same network it simply shows a .pkpass attachment with a question mark(?). If i copy the attached file and paste it into an email and email it to myself it comes back to me with an attachment showing a wallet icon. I click on it and it functions as expected and put it in my wallet. This work around is fine but it would be nice if the .pkpass file was recognized by messenger. I looked for ways to enable or disable certain file types in messenger but can’t find the option. I don’t understand why my wife's phone works perfectly.

Exactly, this works just fine on my wife's phone which is the exact same model and IOS version. I know the tickets are not corrupt because if I email the attached file from Messages to myself it opens right up.

If you can’t open it by tapping on it the file is corrupt; contact the issuer. A valid ticket will open and will have a button to add it to the Apple Wallet.

When you say “messenger” do you mean Facebook Messenger, or the built in Messages app? If it’s Facebook messenger, that is not an Apple product, and you need to contact Meta for any issues with it.

I mean the built in Apple Messages App.

Then I’m stumped; when I get tickets via Messages they always show the Add to Wallet button.
