I only want move alerts during office hours, but I'm getting them during all hours that are not set as "normal sleep time". I thought that there was a setting in Connect Mobile, to specify between which times the move alerts should be active and on which days of the week. But I can't find it in GCM and also not in Connect. Where is it? Did it disappear? Or was it never there, it's possible I am mixing up the Fenix 3 with some another activity tracker. The last time I used the Fenix 3 as an activity tracker was in April so things may have changed.
The only times you don't get them are around your configured sleep times - it's the same on all Garmin devices.
You'll even get them if you've doubled your daily goal. It's a "what have you done lately" thing. (not enough steps in the last hour, it wants you to move)
What you might want to do is turn off the move alerts, and just go by the move bar shown on many watchfaces (that's how I do it), and only pay attention to the move bar during the times you want.
