Google brought its Google Play Movies and TV app to iOS Wednesday, making it easier for users of the service to watch rented and bought videos on their iPad or iPhone. The app also includes Chromecast support, making it possible to beam titles to Chromecast-equipped TV screens. However, there’s one thing amiss: Users won’t actually be able to rent or buy any movies or TV shows through the app — Google apparently wasn’t willing to send Apple checks for its 30 percent cut on in-app purchases.
