We would like an In App Purchase module that can be used WITHIN Expo, ie using the managed workflow and not requiring an eject. Also, we would ideally like the module to provide back-end tracking of user behaviors (eg subscription cancel, revenue recognized, etc). I commented on the existing InAppPurchase feature request, and can add more details here if needed. Yes, this would require overcoming the technical challenges regarding certificates, dealing with Apple/Google requirements, etc. Thank you.
