Install iOS 10.3.3 if You Rent Movies via iTunes
If you failed to install iOS 10.3, iOS 10.3.1 or iOS 10.3.2, iOS 10.3.3 will bring a long list of new features with it. This is one of our favorites.
If you rent movies via iTunes, you'll probably want to download the latest version of iTunes and the iOS 10.3.3 update today.
If you download the latest version of iTunes (iTunes 12.6) and iOS 10.3.3, you'll be able to rent a movie and watch it across all of your devices.
Before the iTunes 12.6 update and the iOS 10.3 release, an iTunes movie rental was only available on one device at a time.
Again, you need iOS 10.3.3/iOS 10.3.2/iOS 10.3.1/iOS 10.3 and the latest version of iTunes installed installed in order to use this.
If you own an AppleTV you'll need to have tvOS 10.2 installed in order to take advantage of this awesome feature.
