Since updating my Charge 6 to the latest firmware, I've had major issues getting it to share HR with apps on my phone (tested with Strava and Wahoo).
I eventually discovered that the only way to get it working is to unpair the Fitbit from my phone's Bluetooth, restart the Fitbit and then begin sharing again. It then re-pairs with my phone and works fine... Until it disconnects at the end of my workout and I have to repeat the process.. every time I want to share the HR data.
Given that this also resets my workout settings to default every time (eg HR zone notifications, which are super annoying mid-run), it's incredibly frustrating.
