The always bad Android app seems to have gotten worse lately .. I don't know if it's just me but I cannot get it to produce boarding cards for multi passenger bookings at all now
Previously if travelling with the family normally I could eventually persuade it to get my boarding card and with some coaxing get the kids too .. but it would never produce one for my wife, but she'd usually be able to get one from the app on her phone
However on several recent trips I can't get the app to do anything ...I just get this message

Going to the view and manage check in and boarding details I can do OLCI .. but it thinks it's generating a boarding card but doesn't actually download it anywhere
It's not just this booking ... Have had this problem on different bookings too
