Hello, we have an app in which you have coins. Those coins can be used in iOS app, Android app and the web application for messaging another user. Questions:
Can we use external payment gateway and the in-app browser to make the purchase for the coins?
Can we accept payments from our WEB app and provide the purchased coins to the iOS use account. ?
If user purchase coins from IAP can they be used in the Android or the WEB application in terms of Apple legal matter.
Thanks In advance.
