I had a bug earlier where I wasn't able to add a Connect IQ data field as it said I was using 2/2. I was definitely only using 1 so I disabled all fields and tried again. Eventually I uninstalled all third party add ons and then reinstalled them, which solved that problem. The only issue now is that, despite showing as enabled, neither the Heart Rate or HR Zone Gauge screens are displaying once the activity starts.
Anybody had this issue before?
