Automatic downloads: purchases on iPhone not appearing on iPad and vice versa
I've noticed that automatic downloads between these two devices is not working. If I buy/get an app on my iPhone 5, it instantly appears on my MacBook Air, but does not load onto my iPad 3, and vice versa, and if I buy/get something on the iPad it doesn't appear on the 5S.
I've tried logging out of the iTunes Store on all devices and logging back in, logging out of iCloud and back in.
I've checked and double checked the settings. Automatic downloads is enabled on the iPhone and iPad. "Install new apps" is checked in iTunes.
Any ideas?
Thanks,
Rob
