@rjpb0731 I am also having the same issue with the original Suunto 9 Peak (not the pro) and it’s a new problem, I’ve had this watch several years without issue. There is a bug in the App apparently that will not accept the Sync from the watch, for both Birth Year, and Height too. Which is annoying, because I’m a short dude and the app is mockingly telling me I’m 5’11’'.
My concern, is that the calorie calculations are now wrong. Please fix this right now
