Ok found out the issue with Ticketmaster. On the ticket app and online site if you click your barcode it is a rotating ticket meaning it refreshes every 3 seconds. By the time you try and download to Apple wallet it has already rotated to a different barcode. Because of this you are unable to download to wallet. Ticketmaster assured me that you can use the rotating ticket from the Ticketmaster app itself. Went to U2 concert over the weekend and they took barcode no problem, even though the venue requested tickets be downloaded to wallet. So on Ticketmaster, pull up your barcode and if you see the line going across it won’t be able to be downloaded. Hope that makes sense.
