Landscape / full screen trailers on iOS app?
I am using version 11.7 of the IMDB app on an iPhone Xs with iOS 14.4. When I play a trailer in the app, there is no full screen option. I tried rotating my phone so the screen is landscape, expecting the video to rotate and expand to full screen as usual, but nothing happens - the trailer continues to play in the top 1/3rd or so of the screen, in portrait orientation.
I checked the FAQs and other forum posts - I found this similar post where a lot of ppl on Android had the same problem and temporarily resolved it by clearing app storage cache. I don't think the iOS app has any cache clearing option like that, at least I couldn't find it. I also found this post with no answers.
I also uninstalled and re-installed the app, with no change.
Surely this is possible, what am I doing wrong?
