As can hopefully be seen from the screenshots, the zones of the intervals on the calendar don’t match zones when viewing the activity. The first interval on the calendar has color of Z2, but the interval itself is Z1 inside the activity. Same goes for the 4th interval and the very last one.
I’ve also added a screenshot my zone settings. Everything should be Pace based.
Is this a bug, or am I not understanding how this works?
P.S.: Thanks for making such an awesome product!
