JUCE Developer with iOS and IAP experience

We have an app made with JUCE which can run on mobiles (Android and iOS).

Using our JUCE code, we would like to supersede the existing non-juce code which exists on the iOS app store.

The app has a singular non-consumable IAP which when purchased, gives the user full functionality.

Our current IAP purchase system in JUCE is using a 3rd party code which is working well, but fails to restore IAP licenses of our old users who had purchased the non-juce app on the app store.

We are looking for somebody who could rewrite the code for the IAP in JUCE (for iOS only), so that the app can be purchased by a new users, and also be restored for old users.

Thanks for your help, please feel free to msg me :blush:

Warm wishes,
Aman
