Yeah, it happened to me too trying to play a few movies. One of the many reasons why I’m not currently using the app at all.
The iPad version of the app isn’t in a great spot right now.
I also have this problem with TrueHD audio tracks, but nobody seems to want to even acknowledge the issue or the simple questions I have about it
The whole thing is such a mess. It doesn’t fill me with confidence about the future of the video player apps.
