When I start a Run activity with the 235, my heart rate is no longer recorded.
Oddly, my heart rate is tracked fine from the main menu.
But when I start a run, all I see for heart rate is "--".
I just checked and Garmin Express says my software version is up to date (4.70).
The heart rate monitoring worked great for my first 6 or 7 runs but has stopped working for the past few.
Any suggestions? Thanks!
