I started an activity to track my open water (ocean) paddling. I paddled for about 6 miles and looked down at saw that my distance was still at 0.0. I stopped the activity, saved it, and started a new one. GPS was still showing that I'm traveling 0 mph, 0.0 distance. I went into the Activity settings and selected GPS + Glonass (originally I was on GPS + Galileo) and almost instantly GPS signal was detected. I'm guessing the GPS chip had to be re-initialized or something. Is this a known issue? Are there logs that I can save/send to Garmin to debug?
