I found a strange issue with my iOS devices regarding playing downloaded movies on Apple TV app. Once I downloaded a movie, every time I turned on the airplane mode and tried to play a movie I got the following message: “Connect to Wi-fi to Watch”.
I’ve tried everything, every type of reset, I logged out from iCloud, from Apple TV etc. I even called the Apple Support, but without any luck (it was not their fault, don’t get me wrong)…
After many, many failures of figuring it out… I’ve finally found the problem: device’s language settings. Who would have thought, right?
So, if you run into this issue and you can’t solve it, try to reset your device’s language.
