I love my Fenix 5X but I have had just 2 quirks. I've tried both software versions 2.90 and 2.95 and they both do the same thing.
First, my HR zones in Connect don't transfer to the watch. My first runs had me in Zone 5 for 20 miles but I was actually in Zone 3 most of the time. The HR seems very accurate but the zones are just incorrect. I had to load the HR zones manually into the watch and now it works.
Second, my watch will show that I hit my 10,000 permanent goal at random points above 10,000. It will show at 10,450 or 11,702 or never. Both the watch and Connect show that my goal is set to permanent at 10,000 and auto goal is off.
Does anyone else have these issues?
