Apps installing on one iPad, but not on others with the same iOS
I have 3 old iPad 4s that are all the same age and on the same iOS, version 10.3.3 (14G60). I am using them in class with my students so that they can play games on them for learning.
I have installed the app Scratch Jnr. on one iPad to do some coding exercises, but it will only install on one of the iPads, the other 2 are saying that it is not compatible.
How can it install on one, but not the other two? This is not the only app it happens with. Is there a setting that stops it installing the latest compatible version, like it asks on other apps?
I understand that some apps won’t be compatible on an older device, but I don’t understand why they work on one, but not on another on exactly the same iOS and device version.
I can’t afford to be buying loads of new iPads, especially when these work perfectly well otherwise. Can anyone advise?
