Just got the 9.20 update a few days ago. Now I can't seem to get the HRM to work anymore. When I go to the settings, "Heart Rate" is toggled off, I toggle it to "auto", and then go back. If I go back into the HRM settings, the toggle is off again. What's up with that? Hard and soft reset didn't seem to do anything.
Is the Wrist Heart Rate setting enabled in your Garmin Connect account? If it is turned off in GC, it is likely that your 735XT is syncing with your account and turning off the setting once more.
If it is turned on in GC, and you still can't get the setting to stay on, post here again so that this can be investigated further.
Just checked Garmin Connect on both Android and web, and Wrist Heart Rate/Heart Rate Monitor setting is on in the device settings. Any other possible issues?
If you are seeing this issue, please reach out to our Product Support team (phone, email, or chat). The teams will be able to collect specific device information in order to get this issue investigated further.
I've had the same problem recently. I usually wear an HR strap (which works fine), but when I've gone without that, seems the wrist HR no longer works, despite being turned on in Garmin Connect. Odd.
