IATATravelPass DOES NOT WORK.
Firstly, you can not do anything if you only login to your iPhone with a passcode. When prompted to sign in to IATATravelPass with my Apple ID and enter my phone passcode, I enter it - but then the spinning “processing” icon just goes snd goes until it times out, going back to the sign in screen. Cannot even sign in, making IATATravelPass totally dysfunctional for people who opt not to use face ID on their iPhone.
I saw another user’s review from a month ago (Aug 2021) reporting the exact same issue, so obviously IATATravelPass developer is either unable or unwilling to fix the issue. But wait - there’s more….
Interestingly, my spouse - who uses face ID to login on his iPhone - WAS able to login and get through the initial setup process. HOWEVER….
* IATATravelPass “could not find” our flight despite repeated attempts, and we are ticketed passengers with a flight coming up in 5 days.
* he could not enter his health documents (from the United States)
* IATATravelPass could not scan the chip in a USA passport, because there is none
Bottom line: TOTALLY USELESS APP!!!
