Wrong itunes account when updating apps
With automatic downloads, every app, e Book, audiobook, and song you download on one device will automatically download on all others with the feature enabled.It can be a huge time saver if you know you're going to want to use or access any of that content across multiple i OS devices.You can't actually view a list of devices associated with your i Tunes account on your i Phone or i Pad.To see that, you'll have to log in via i Tunes on your computer.Sometimes, that can get a little overwhelming and you may want to shut that down.Here's how to enable or disable automatic downloads and updates, and how to make changes to your payment information or unsubscribe to services.The rule of thumb is that if an app won’t download or a song, movie, or TV show won’t play, it’s most likely linked to another Apple ID.
If you have an older device that you don't use anymore, you can de-authorize it, clearing up room for a new device you'd like to add.
From then on, make sure that you use your personal Apple ID for all purchases.
With the release of i OS 8, Apple introduced a new feature called Family Sharing that allows up to 6 people to share purchases made from i Tunes, the App Store, and from i Books.
You can, however, de-authorize an i Phone or i Pad right on the device.
If you wish to re-enable the device, enable Automatic Downloads again or download a previously-purchased app.
