Saving IPHONE apps no longer available App Store
I have an app on both my IPhone & IPad I use all the time for teaching. The app was updated to IOS 11, 64-But everything.
Yesterday I found a message that it was no longer available in the US Apple App Store.
No longer in purchased apps (it was a freebie for teachers/students)
I desperately need this this app for teaching. I know the organization upgraded the App for IOS11. Hard to contact them to ask questions
Any way I can save these apps in my IPhone or IPad if I upgrade my devices? They are sound recordings of animals.
I’m afraid if I upgrade my IPhone or IPad I’ll lose them forever as I cannot download from the App Store at least in the USA.
Any ideas how to save them? And why would an benign educational, well-reviewed app be removed from USA App Store?
Thanks!
