I have tried to use the HRV feature on my F5X and am problems. I have enabled HRV logging under setting. The APP is installed and one of my favorites. I am using a chest strap that is paired and connected and I know its working because when I remove it the HRV apps asks for a chest strap HR montior.
When I start the app the screen with colorful dial comes up, I press start and I get this screen that simply says relax and stand for 3 minutes. I have tried this a few times and waited for 10 minutes but nothing happens. The screen simply stay on giving the same message, no count down, nothing.
I have tried adding and removing the app with no luck.
Am I doing something wrong? Does anyone have any suggestions?
