I have an existing app published on the Google Play store; the app is free with some restrictions and users can upgrade to the Pro edtion to have those restrictions removed by paying a monthly subscription fee.
I want to implement for the PWA the subscrption feature so that PWA users would have a similar, if not identical, experience as Android app users.
How do I get started? If you have some experience dealing with this, could you give me some hints on where to start? That would be greatly appreciated.
