They changed the rules. I don't think you should stop, unless apple says something??? Maybe someone else with more refund experience can reply
Apps are not removed from your device. They continue to run
Apps will not restore from the cloud or itunes if you remove the app. If you delete the app, you can no longer restore the app from purchases..
Im not sure about this, but I thought apple would allow you to keep the app before , even to the point of it being in your itunes library / recent purchases, but it no longer offers this. When I deleted cellular info off of my ipad, I could never get it back.
I forget if I ever had cellular info in my itunes library. Its not there
