Hi
My instinct altimeter gets stuck when recording activities. Most recently we hiked up 430 vert metres to 450m over about an hour , shortly after starting descent watch displayed and recorded altitude as 450m for entire descent. Data sent to Garmin connect was a constant 450m for the rest of the activity. When started to record a new activity altimeter reset to actual altitude. Watch is set to auto calibrate.
Any ideas, is this a software glitch or a hardware problem?
