Ticketmaster offers no alternative to your smartphonw
This might not be news to everyone, but since 2021, they stopped offering an alternative to the app. You can no longer print or screenshot the barcodes because they roll.
Choose your venue / whatever. I. E. I was visiting NYC and went to watch the Yankees. So I search for the Yankees, and my ticket shows up. It will show their fancy barcode thing in the browser and it works just fine.
