Hi, I've been able to successfully use AppsFlyer so far in one of my games across both iOS and Android. All seems to be working well. It appears to be built by Corona and I have a quick question about using the logPurchase function.
When I install my game via TestFlight to do a formal IAP test, and in iOS when I use the logPurchase() function (see http://docs.coronalabs.com/plugin/appsflyer/logPurchase.html), I'm getting an error code 21007. Per this link on Apple docs, it states essentially that the validation call is pointing to production servers at Apple rather than test ones.
