A new one for me: I checked in and downloaded the boarding pass yesterday for my flight today without a problem. This morning the app tells me to retrieve my boarding pass again. Now I have two boarding passes on the ba android app, but both for the outbound a week ago, in 10F and 12F.
12F is the seat for today, but with last week's date and time.

I got myself a paper boarding pass at the airport...

The BA android app is comically bad.
