Garmin 6X Sapphire - issues with altimeter and Barometer calibration failed. Tried multiple times to calibrate, factory reset, updated multiple times to most updated software in Garmin Express. Altimeter freezes to last recorded elevation and no movement thereafter. Any help possible from Garmin? To add to all this, moving pace is not displayed in Garmin connect and Vo2 maz shows 6 days old data.
