I'm going to continue to ##### about my watch forever --- but I am so fed up with it right now. My music is finally playing correctly when wearing it on my left wrist, but the new thing is that is tracking my cadence as my HR.
This apparently is not a software issue but a hardware limitation of the optical sensor. From what I read, what it is really doing is doing a weighted average of my cadence and my actual HR, with the likely cause being that taking the watch from inside temperatures to outside temperatures creates condensation on the sensor that then is unable to track/penetrate to the correct spot for your HR. If this is the case, it would also make sense why a lot of times my HR is elevated at the beginning of the run, but then the temperature gets regulated and works fine.
Not sure if anyone else had experienced this, but it looks like my possible solutions (at least on colder days), are to wear the watch tighter than usual to eliminate any sort of condensation buildup and/or to cool the watch, by having it outside or in the fridge, prior to running. The latter supposedly may only work until my body heat warms it back up, but may buy some time.
I'm going to play around with these ideas and see if I can get it tracking correctly, or I may just have to wait for warmer weather.
