Our watch will not start. It may get to the watch screen but the it shuts down. Already removed it from my updated app and tried the 10 button back press to no avail. We have 2 watches and they both have had issues requiring a reset. Now this one will not reset and while on the charger it goes from 14% to 93% then to 41% to 100% is a matter of minutes. I am becoming frustrated with these issues that come up every couple of months. How do I factory reset this watch when none of the fixes in this forum do not work?
