When you say “wrong way around”, do you mean turned 90 degrees? If so, this could be a case where the app thinks it’s in portrait mode when it of course actually should be in landscape. You could try installing an app to force landscape mode and see if that helps. See this thread: Default "Force landscape" or add option to change the orientation. I’m not sure if that helps with the app closing though. It might, it might not.
Also, which version of the NowTV app have you downloaded? My quick check on the Aptoide web site showed that there are different versions to choose from.
Also 2: great to hear that you’re liking it! Looking forward to getting mine any day now.
