There is one app that I want to transfer from my iPad 4 to my iPad Pro. But will not transfer. The app is not available in the App Store anymore. Any way to transfer the app other than iTunes.
Nope. OTA from the app store or from iTunes in your computer.
OTA from the app STORE. Which already said you cannot do because rhe app is no longer abailable.Over The Air from the app. How does this work?
