Instructions:
Streams can pause for many reasons, including accidental tapping of the Pause button, leaving the app, or losing cell signal.
To remedy this:
Force quit the application. Ensure cell service is viable via your device's dashboard.
If service is sufficient, reopen the app and return to your stream by pressing the green camera button in the lower center of the screen.
From here, you will be prompted to Rejoin stream.
Additional Info:
Regularly checking your signal strength and app settings can help prevent unintended pauses.
