I have set up Products, Packages, and an Offering in RC and can see it in my app (using Expo + react-native-purchases SDK). When I complete a sandbox purchase it is neither appearing in the Purchases.getCustomerInfo() response nor the RC admin console.
I also have ensured that I set the user ID with Purchases.logIn().
(I did not set up a sandbox user in App Store Connect but I presume that using my actual Apple account for sandbox transactions is okay.)
What am I doing wrong?
