If you’re having any trouble with getting the App to work properly, try these steps:

1. Start the Settings app and find Battery Optimization in the Apps section.
2. At the top of the screen, tap “Not Optimized” and then tap “All apps.” You should now see a list of all the apps on your phone. Each app is marked “Allowed” or “Not allowed.” Allowed means that your phone is allowed to put the app to sleep when it’s in the background.
3.  Find an app that you don’t want to go to sleep, and tap it. In the pop-up, choose “Don’t allow” and confirm your choice by tapping “OK.”

1. Low Power Mode (Settings App – > Battery – > Low Power Mode) needs to be off
2. Background App Refresh (Settings App -> Hushed – > Background App Refresh needs to be ON
3. If Background refresh is greyed out in the ON position, go To Settings App – > General – > Background App Refresh – > Turn on the option for the system, and then you can turn on / off by app.
