Currently I use a separate backend to acknowledge purchases (Subscriptions & One-time products) made from Google Play.
But when a user cancels a subscription from Google Play app, and leaves my app in background, there is no way for me to know that user is no longer subscribed so that I can refresh app content for example.
So is there a way that Google Play notifies me when the subscriptions get canceled?
Note: Backend already sends a notification (Firebase notification) to my app when this cancellation happens; but when the app is in the background and the user opens the app again normally (not by clicking on the notification banner) I can't catch this notification.
