@MarkHoltom Few months ago I couldn't access a museum because you can buy tickets only online, but you couldn't pay with credit card, only online transfer or "pay later" system, neither of which worked because both required 2FA from my bank app which was temporarily broken (again). When it fixed itself, museum website decided to no longer send reservation e-mails from which you're supposed to make payment. After 30 minutes of brutal battle in 30 ⁰C I had to forfeit the visit.

@MarkHoltom Best part is, nobody from staff was surprised, they had to denied access to a family with children because they were unable to buy tickets as well. It's not that they didn't want to help, they were simply disallowed to sell tickets on site and couldn't access the system, only scan QR codes. It was in #gdansk in case you wonder.
