I got tickets for a concert in UK, which could only be bought if you had UK Ticketmaster app. No, the international version of Ticketmaster app did not have these. Had to get me a blank Android phone, had to initialize it pretending I'm in UK via VPN, so I can see the UK Android Playstore (got my phone number blocked by Google in the process - "too many verifications from this number"). Then, it finally let me get the tickets and actually see the dreadful barcode in the app.

This is horrible. Please stop.
