Awkward app on multiple fronts

It does get certain jobs done (check-in, give travel info etc.) — but there is lots of room for improvements.
For instance, each time you want to go back to your reservation information, you have to re-type your confirmation number and last name, even within the same session, which is really awkward.
When I scanned my passport, the app uploads it but then it complained that my name was incorrect — which was not true, but it did not get my middle name. There is no way to correct or add that. You can only cancel the process. So, the whole check-in process is cancelled because of this flaw.
After I had checked in (without passport, which is possible) using the app said the boarding passes will be emailed. But they weren’t. I only got an email notification that my check-in had failed. So, what’s the point? Why not just say that in the app?
