I’m working on a Flutter application that implements subscriptions using in-app purchases (IAP).
I currently have two apps under the same developer account:
One for staging One for production
In App A (staging), I successfully created a monthly subscription with the product ID: rc_1299_monthly
However, when I try to create a subscription with the same product ID (rc_1299_monthly) in App B (production), I encounter the following error:
"The Product ID you entered is already being used by another subscription."
My understanding was that product IDs are scoped per app, but this error suggests there may be account-level constraints.
Has anyone encountered this before?
Is it required to use unique product IDs across all apps under the same account, or is there a recommended approach for handling staging vs production setups?
Any clarification or best practices would be appreciated.
