Not sure if the is Connect problem, but data shows correctly on the VAR/Fenix so suspect something is happening in the data transfer. Exercise is recorded using the Fenix with a HR strap.
Unfortunately, I can't upload a screen capture.
Basically, exercise over, sync over WiFi - not issue, but when I view my HR is flat line at about 150 for the rest of today (VAHR data). If I drill down and look at the activity details everything looks perfect, and on the screen of the VAHR everything is OK.
My VAHR sync over BT to my phone, the Fenix I need to directly connect to the laptop (as I have an Edge that is also configured for the phone). Last week exactly the same happen.
