My Alta seems to track my "go to sleep time" accurately. However, if I awaken and lay in bed awake an hour or even longer, my Alta still tracks me as sleeping until I get out of bed, Why? Can this be fixed?

Without heart rate sensor, all it can go by is your movement.  If you are lying still, it cannot tell if you are awake or asleep.  The models with heart rate can use that data to help determine when you are asleep.

I expect that if you move your arm around enough after you wake, then it will know.

Before posting, re-read to see if it would make sense to someone else not looking at your Fitbit or phone.
