Android app won't stay in landscape mode

The FlightAware Android app stays in landscape mode for one second and then swings back to portrait mode, even if the cell phone is horizontal.

Although I get that you appear to be on somewhat ‘for the people’ crusade after a similar campaign on Flightradar24 in previous years.

Surely including a bit more detail like OS, Screen size and so on would actually be found beneficial by the developers if you want your reported issues/requests to be investigated/actioned if they actually take note at all?

I can’t speak for others. But rotation is not even an app feature on my android13, 2400 x 1080, 6.4" device running 5.8.0
So a split second thing is less likely experienced across the board.
