Hello,
I am making the user purchase subscriptions from Google Play and Apple Store with Unity IAP. I want to register the subscription with the user's Firebase Auth E-Mail after the Unity IAP purchase using RevenueCat. I want to ensure that the user can use the subscription from Android or IOS device without losing it. How should I do this using RevenueCat? Unfortunately, your technical documents were not enough. Can you help me?
Thank you...
