I am in the USA. I am using an iPhone 15 with IOS 18.5. I have registered with the Sbb.ch website using my computer and when I use the Website on my computer it shows I am logged on. When I go to Profile / Logon on the SBB mobile app on my iphone, I just get a red screen. It never asks me for my email login id or a password. I have deleted the app and reinstalled and turned off phone multiple times with the same result. I don’t see any way to contact you directly. I travel to your country at the end of August and really need this to work.
