I have a Google Pixel Watch and a Pixel Phone (Android). My heartrate seems to be tracked correctly and I'm getting Zone minutes reported correctly for the day. But in the "Exercises" section, it's not adding up zone minutes. I had an activity where the graph showed that I was in the red "cardio" zone for most of the time, with a bit in the yellow "fat burn", but it's telling me "100% below zones" for that exercise and giving me zero minutes of cardio or fat burn. The heart rate section, however, gives me zone minutes for that time. \
Fixed: In case anyone finds this, the solution for me was to reconnect the watch to the app by choosing to "Set up an Device". It replaced my existing watch without losing any data and future exercise logs recorded properly/
