Just a couple days ago I got the notification that a new software was available, I installed it. Since then, my watch has been spazzing out with the heart rate. It will go from 50 beats to 80 to 120 beats all while I am sitting down. Even the chart of last four hours is flat with a bunch of random spikes. This just started happening after the last update. Anyone else experience this after doing an update? Also, when I run, all it shows for the heart rate are two dashed lines. Like I said I haven't had this problem and yes the watch is on tight enough.
If the device stops responding, you may need to reset it.
NOTE: Resetting the device may erase your data or settings.
Hold power button for 15 seconds.
The device turns off.
Hold power button for one second to turn on the device.
I think the issue was a third party watch face I downloaded through connect IQ. When I uninstalled it, the heart rate function started working no problem.
Could you tell me which watch face it was that caused this. I had similar issues and after calling Garmin support, they could not resolve and are sending me new watch (should be here tomorrow.)
