Since the 4.9.1 update, steps and other such data are no longer synced from the Connect app to the Apple health app. I am using a Fenix 5 with ios 11.4.1
Yes, that is correct. Unfortunately for us, the consumers, Garmin has decided to not publicly acknowledge the existence of this bug. We can only hope they are even aware of it. But at this point, I wouldn’t bet money on it. They don’t seem to spend too much time in their own forums.
