Maybe I'm wrong but when i had my iPP 12.9 first generation all the downloaded movies were 720P, Now with new iPP 12.9 second generation download movies are 1080P. I found out that because of download size compare to movie info on iTunes.
I still prefer 720P to 1080P due to storage size, So the question is how can i be sure my download movie from iTunes app is 720P? Besides I never use PC version of iTunes and don't need to connect my device to PC.
Just tell me where is the settings of the quality of HD movies/shows on iPad Pro?
Edit: Solved All iPad Pros download 1080P only. So there is no way back to 720P?
