Is it possible to jailbreak the app?

Question

iOS

1) The iOS app has in-app purchases (meaning that after making an in-app purchase, the app will become a PRO version).
Jailbreak is powerless here and in order to use the PRO version of the application, you have to buy the application?
2) Let's say there is a jailbreak on the iphone.
The application in the app store has 2 versions: Lite and Pro.
If you download the .ipa file of the Pro version of the application (for example, take the .ipa file from another apple id account that has already purchased the Pro version of the application), will it be possible to install it on an iphone with a jailbreak?

Answer 1

If free and pro are in the same application, then usually without any problems (and without jailbreak) you can get the pro version from free.
If the applications are separate, the free is free, but the pro is paid - you can’t get it here except to buy it.
Applications can be hacked without jailbreak.
