Puls not accurate after new update. I just had my first work out after the recent update on my Garmin vivoactive 4s.
I know my work outs, and my kardio usually gets my puls up high. Usually 190-200 when at it's most intense. But during this workout, my garmin only got a puls reading in the 130ies on the first round. I tried restarung the watch. Then during the next workout the puls got to the 150ies at most. I've done all the basic stuff to make sure it can read my puls, and restarting and so on. Nothing is working. Even in the testing time after the workout, when I know my puls is still high, it's reading in the 80ies....
I've tried another fitness watch getting an update and that ruined the watchs puls function. Thats why I even got a garmin, and know this one is doing the extac same after an update..
