My payment went through OK with app authorisation for the Klopp event, but I must have done about 50 captchas at least, no exaggeration, I was doing 10 in a row for each page! When I tried to pay I first got an error and then got into another endless cycle of captchas, I was screenshotting everything convinced I'd lose the tickets but eventually a refresh let me through to pay. Absolute shitshow and not even for match tickets!
