Hello,
i've come across this problem (also on the beta 12.20)
I've seen in the 955 forum that it is a common fault. Do i need to put this here in the 255 section also?
have to get this of my chest: since i've purchased the watch it only has disappointing software bugs. My first 4 Garmins never had one issue. I'm really getting frustrated spending 400 euro's on a watch which now has screwed up al my training load's en stats thus far......
