The compulsory function that requires a travel document check is pointless, especially if that information is already saved in the profile. Its also annoying, and you should consider removing it.
Ive also said this before, Ill say it again: when we the ability to change flights within the app be added?
The Air France app offers this feature, and it doesnt ask me 100 times to verify my passport. Its also a much better app than KLM. Both airlines belong to the group, so one would expect to see a little more parity with these sorts of little things.
