Hello Community
We have developed an app 3 years ago which offered In-app sessions for purchasing. Users were able to restore the sessions if they use the app on another device.
Recently, we overhauled the app completely with the new user interface (UI Design) but kept the same In-app sessions.
Now there is an issue being faced in latest versions (iOS 11 & 12) that existing app users are not able to restore their In-app purchases. Although the restoring option is working for new users on the app.
We are using Xcode 10, Non-consumable in-app.
Can someone advise on this and provide the solution.
