My watch is about 16 hours old now, I did all the updates before it was put on. I assume this is a firmware issue.
My abnormal Low HR alarm kept going off , It said your HR was dropped below 110. (This is the message for Lower HR threshold )
Note all the alerts pictured below are for LOW HR, they are well above the 55 set and under the 120 ,, It is odd that the watch says 110 threshold
The watch was synced several times, I have set them up and down by 10 bpm, trying to force the change. But no joy.
I just noticed, on the watch, you can set thresholds during the alarm, and sure enough, the LOW HR was set to 110, which is not even possible in the Connect software. Odd it is outside of the range that can be set, Im Hoping that next sync it says with real values.
I verified the settings.
