In the period of a 5 months, I've noticed that in exact conditions, same subject, and in the same location that the active track is losing the subject (slow bicyclist) more often than not.  Seems to guessing and locking onto other objects which wasn't the case prior to the previous firmware.

Anyone else experiencing this?   

Yep! Had this multiply times.

What worked for me was highering the drone upto 15 meters!

Thanks for the reply.   So going higher seemed to make it easier for tracking?   Interesting.   Perhaps the spark doesn't have to maneuver as rapidly when up 15 meters.   
I do admit that i was half that.

Yes, I noticed the Active Track was rock solid my first two months owning the Spark. Into my 3rd month and Active Track just doesn't seem that rock solid as it had before?

I'm going to do some more testing in Active Track to see if it was something by way of the Sun or clouds being the problem as opposed to the software or hardware being the problem?

I've noticed that yawing the aircraft is jerky at best when I take video...but if I climb and increase the camera angle down, the panning/yawing gets smoother.  I wonder if this is the case in tracking...with the camera up the jerkiness of yaw is more pronounced as it tries to track and it loses sight of the subject easier.

Yes, areas where more yaw was involved generated a slower stutter and eventually lose track (or lock onto something else completely different).    Still it seemed to work better months back for handling.  I'd just lose a subject when it went from bright sun to a shaded area.

Please try to track a slowing moving object. If you have video, please provide it to us for further check. Thanks for your support.
