Hi - I have a Garmin Forerunner 301 with HR monitor that I'm using with Garmin Connect. All sw is up to date. When I edit the HR training zones in My Profile on GC and hit Save, they are not saved, and keep reverting to old values. It doesn't matter if I try to edit the default, the running or the cycling zones, none of them will stick. When I hit 'Send to Device' all the old values get sent, not the values I've put in. I know that the 301 is old and does not support the resting HR data, but even if I leave that blank and just edit the bpm for the different zones it still won't save.
The result is that GC holds different HR zone data than the 301, so I can't analyze work in various zones on GC cos the data it shows is incorrect.
