Itunes rental
I can't download 2 movies I rented on itunes.on my ipad2. I already deleted some apps. I have 3 gb available. They don't even appear on my purchased films to try to download them. I already paid for the rental.
iPad 2, iOS 9.2.1
You have to sync it from your Mac:
If you rented the movie on your computer, but want to watch it on an iOS device, connect the devices and sync using USB. When you move a rented movie from your computer, it will disappear from your computer’s iTunes library. You can move the movie between devices as often as you want, but you can only have it on one device at a time.
If you rented the movie on your iOS device or Apple TV, you can’t move it to any other device.
