Same boat exactly. Bought my first gen within the first month after release, worn night and day ever since. Heart monitor has gone out a couple of times in the past, but a shutdown and restart always restored it. 2 days ago heart rate froze while I was running, LEDs off, and it hasn't come back on since. At least 20 restarts, updated phone ap, cleared cache, uninstalled and reinstalled ap, changed clock face, flashed a firmware update and did a full factory reset. All have failed. Previously had a Charge HR and Alta all have failed around 2 years. I'm starting to think that there's an element of planned obsolescence here; seriously considering moving to a Garmin or Samsung.
