I should mention that app purchases fully work on my iOS devices...
Is RevenueCat supported on Designed for iPad targets or not?
Hey @3DTOPO ,
The error you are getting is likely due to the sandbox environment being flakey. For Sandbox testing, you may have to make a purchase to generate a receipt before attempting the operation. In Sandbox a receipt is generated when a user makes a purchase and is saved against the sandbox account. While in production a receipt is generated when a user downloads the app and is saved against the Apple account.
For MacOs, we have the following requirements:
Xcode 13.3.1+
Minimum target: iOS 11.0+
