Ios App Is No Longer Available

The transfer process was relatively painless.
Ios app is no longer available. Then i have the following questions. Some folks have resorted to buying used iphones and ipads on the internet that contain the app they want. We ourselves have a couple of apps that we removed from the app store years ago and stopped development on.
To get started make sure you are using the same apple id that was used to download or purchase the unavailable app. It s not likely that many of these apps will be updated especially those that were no longer available on the app store before ios 11. If you can find the app you want to use just add it your iphone the developer will probably offer instructions and you.
If your daughter has her iphone synced with another mac or pc you can copy that file to the same folder on her system then launch itunes and plug in the iphone. First fire up the app store then tap on the account icon in the top right corner. Later i resubmit again to test.
I have an app on my iphone 4s called 7 second diet. I still have the app on my iphone 4s. Two days ago i bought a iphone 6s.
The app should then be available. Following that open the app store in your iphone ipad and tap on your profile picture. Most iphone apps are only available in the app store not for direct download from the developer s website or another source.
You should find it on the top right corner of your screen. First is get invalid product id when i am trying to get information about product. Luckily it is still available on my iphone 4s.
