While I was going through my " All warnings" section on my Go app I came across two warnings on different flights about a "Stuck Compass" is it somthing to be concerened about?, both flights the message is on were faultless and there not showing up on the flight records. I must admit I haven't callibrated the compass for sometime now as i'ts never asked me to, or was it somthing to do with being cold?. The warning is at the bottom of each picture

I got that warning too - last flight.  It popped up when I tried to auto-launch.  I calibrated the compass and it didn't pop up again.  I almost missed the sunset though...

I'd also be concerned about your attempt to fly with a cold battery.
