Due to artificial limitations of the operating system providers, the correct functionality of this action is difficult to ensure. Using this action on Android more than once during a short period of time (e.g. less than a month) might not always display a dialog. On iOS the prompt will not show in TestFlight versions of the app. The system prompts the user a maximum of three times within a 365-day period. Furthermore, the mos. iOS app does not respect the async flag in this case.
