Anyone STILL having heart rate accuracy issues with their Fenix 6?

OK, so I opened a support ticket and they responded later the same day which is great.  They suggested a soft reset which is holding the power button for a full 20 seconds, wait a few seconds and then power back on.  I did that and then also did another test where I wore the F6 as normal for me which means it slides down to very close to my hand and I have bony wrists as well.  I noticed that my old Fenix 3 HR was sensitive to this given my bony lower arm and wrist....so I tried to wear the Fenix 6 a bit higher up my arm by about 1 inch (like the picture further up this thread).  It worked!   Both in normal watch mode and also when I turned on an activity (indoor cycling), the hear rate was very close to a chest strap I wore and monitored through my phone app.  So, I'll keep up with this approach and it may work for others to make sure the watch has enough 'flesh" under it by moving the watch up the arm just a bit.  Another learning...I have a Wahoo Tickr Fit optical arm band and to get a good reading I have to wear it just up my forearm a bit so there is good flesh under it.  If the arm band is too low on the arm where the arm/wrist bones are closer to the skin surface it won't work well.  I think that's a common problem with optical sensors.  I'll keep trying to wear the watch an inch or so up the arm and away from the wrist bones and see if that helps.  The support ticket person also said to just return it for a new watch if it keeps happening so I agree with others that part of all of this mess may also be a hardware or software problem....my old Fenix 3 HR didn't have these sorts of problems nearly as often and wasn't quite as sensitive to the placement on the wrist.
