Since a few days ago, my Edge 830 has stopped registering the time spent in Z7 power zone. It all started around May 22nd. On May 20th it registered perfectly, and none of my rides since then have registered any Z7 time.
All rides (working and none working) have been done using 9.75 firmware. And I've checked the ride summary after stopping the activity and before giving the device the chance to sync and the Z7 is already missing in the summary
Those same activities show the Z7 time just fine in TrainingPeaks or Strava, all are using the same zone definitions and all get the activity information from Garmin
Is it just me? Any clue what might be happening?
Thanks!!
