This recording error typically indicates a connection issue. You may need to Reset and re-establish the connection to the GoPro:
Reset the GoPro to factory settings by navigating to [Preferences] - [Reset] - [Factory Reset]
Install/open the GoPro Quik App and connect the GoPro to it.
Once connected, give GoPro a custom name.
Test the live view by tapping [Enable Preview] on the Quik app (this will force the GoPro to connect to a device using WiFi)
Once this is confirmed working, close the Quik app
Then open the Snappic app, select your event, and test the GoPro connection
*It is crucial to have the GoPro connected on the Quik app page before attempting to film using a wired or wireless connection
