So I'm still trying to narrow this down, but it seems as though the HR is not being accurately tracked after starting a new activity. Here are the observations so far.
Start fenix 5x for an elliptical activity.
Start workout.
A couple min in I notice my HR is still showing 60-70.
I can tell it's higher.
Grab the elliptical HR monitor and measure HR in the 130's
Stop fenix 5x activity. Restart fenix 5x activity.
Fenix immediately starts ramping the HR up to 130's and tracks correctly for rest of workout.
Anyone else? I'm running the 7.93 beta, but almost certain I saw this in 7.6 as well.
Other than that, life with Fenix 5x is great (sarcasm). This is just the latest from their random data generator fitness watch.
