Unable to add any passes or tickets to Apple Wallet after iOS 15.5 upgrade.

Thanks but that isn’t the issue. I’ve been using Wallet for many years. Just last week this problem began after I did the upgrade. Clicking on the Add to Wallet icon goes nowhere — for tickets, for my Genius Bar appointment, etc.

Solved - seems the problem was that I was using Firefox for gmail. Using Safari allowed the Add to Wallet function to work. From the same email, worked in Safari, didn’t work in Firefox.
