Off line in app purchases don’t work

Is there any way to make in app purchases just disappear once purchased and not need to be checked every time the app is opened
I have canceled subscriptions before because I was on a plane or high on a mountain with no internet connection only to find that I couldn’t use the full program
it’s a pet hate of mine and now I have it in my own app.
I am not the programmer of my app
I would really like to point the great person doing the programming In the right direction.
is it possible?
yes or no would be fine.
i see the need for restore in app purchases if you buy a new phone and my app has that but I would love not to have to go through this process every time I open it.
