How often should I verify a auto renew subscriptions?
1x at every app launch? Meaning the customer presses the app icon and launches the app?
Or 1x when the app is initially launched then allow the app to reset in the background if it is not opened for a while? iOS will reset the app after some time. It will then recheck at launch again since the app was reset by iOS. If the customer comes back to the app before it is reset it will not need to check the subscription again.
