Thanks all. It’s a personal ipad. Set up as a child within our apple ‘family sharing’.
We do get the approval requests for other apps when he tries to install them.
I have a Minecraft Education license but on the pc version there’s no restriction on installing it, but you need the log in to use it. Id assumed the ipad would be the same. Maybe it is the age thing as suggested. It’s minecraft education rather than minecraft if that makes any difference to the age or otherwise.
Ill check the ios. However, i thought it usually told you if it was too out of date – that’s what happened on an old ipad we had that stopped being updated by apple.
