i was the first to purchase this app even though it was very over priced. i was promised that the app would work in my country and the gateway would also work. none of the above info they provided was true. the gateway provided on this app is Razorpay which can only be use in India. They blamed all the issues of this app on Firebase and finally told me they dont have control over firebase and stop responding to my messages. I bought the app for $199, paid $450 for installation, $250 for customization and another $250 for features, all that money spent was a waste... be careful
