We are aware of some intermittent issues with the PAI app, and while we are working on improving the user experience, we have some suggested workaround solutions that can help in the meantime.
ISSUE: SLICE disconnects from PAI app. You may notice your SLICE doesn’t stay connected to the PAI app. You can tell by going to “MORE” section on your app, and you will see SLICE is in grey and it will show “Not connected”.
WORKAROUND: Check that your GPS/Location is turned on. Turn Bluetooth off and back on. Forget SLICE from the "MORE" section of the PAI app and re-add. You can also try force closing the app and re-opening it.
