Definitely not an activity tracker, at all

I was elated when my polar workouts also synced the HR data into oura. I started looking at my weekly HR zones, and getting into it. I have done 2 workouts this week that definitely got into Zone 3, maybe even zone 4, but my weekly zones show nothing but zone 1. I drill into the workouts and now it's using oura HR data (which lets be honest, is absolute sh*t) instead of importing it from my polar.... how disappointing, don't fall for any feature of the activity module being reliable.
