We've been using Distriqt ANEs exclusively for the past two or three years. They are really great and Michael keeps them up to date. Can't say enough good about them. We are using Distriqt's Firebase Push Notifications, Application, Scanner, Dialog, PDF Reader, Local Auth (biometrics auth), Native Web View, and Network Info ANEs. We don't use in-app-purchases so I can't vouch specifically for that one, but Distriqt is the one vendor dependency we have that we don't worry about. I can't say that about plenty of other dependencies in creating AIR apps for Android and Apple.
