The auto-track activities function is not working on my Pixel Watch 2. In the fitbit app, I made sure the setting "track automatically" is enabled and the minimum duration is set to 5 mins for outdoor biking. However, when I bike for more than 5 mins, Fitbit didn't track it. I did, at some point (unsure when but not the first minute), receive a notification asking if I was biking and if it should start tracking. But I assume this is not the auto-track function. If I understand correctly, the function should track activities without me having to agree.
I've updated my watch, Fitbit app on my phone and on my watch to the latest version. I also tried restarting my watch, but none of that helped.
