More info: the landscape "trick" worked only when I came in via the App. When I tried coming in via Safari the screen did nothing when I rotated the phone to landscape view. Could just be my phone has Safari locked in portrait mode, YMMV.Reminder you need to scroll down in landscape orientation to see the Wallet button. That did the trick for me on iPh 13 w latest security patches. My wife was stunned this worked.
For doubters, here is a link to the article that suggested trying this:
Add to Apple Wallet is missing - Apple Community

Someone else recommended refreshing/updating the app. I think I may have deleted and reinstalled it before the last home game.
Hope this helps.
