Regarding handyticket.de Thanks. Is this due to https limitations in phoneme? Btw, I tried, without https it works as intended. (How unsafe is this practically? - I changed my pin after trying via web). But there ist one additional problem: After buying a ticket, it comes as a QR code. This is displayed correctly, but a "zurück" (back) status bar obscures a few lines of the code. Any way around this?
