It has never worked for me. I'm running 10.2.1 on an iPhone 7. The app displays a blank page and then crashes after a few seconds. I tried deleting and re downloading it. I use the US App Store, but I live in Japan and have a SoftBank SIM. The phone model is MNCM2J/A. Could that have something to do with it? This sucks because I can't watch movies I bought from iTunes. And the Video app seems to be gone from the store.
