Anyone else having trouble posting issues on the forum?   My strap is erratic with heartbeat (drops out to ZERO during exercise) and registering 30-50% higher than my actual breathing rate (I count and compare to strap).   My heart strain instantly goes to .25 (never anything else) and stays there - always.  My forum posts keep staying "in moderation."   Contact me if you are having issues. I just want this expensive jewelry to work like my other HRMS do!
