New feature in DJI GO 4 4.2.6 app
"Gimbal pitch tracking enabled" is added in app.
So if it is active, camera can follow you? ... I have not checked yet...

sounds like something that would work with active-track as elevation changed - have not had a chance with it - AC back with DJI for the moment.

Adjust the gimbal’s tilt by rotating your mobile device after tapping this icon-manual information about it...
I supose its only work when driving dron without RC.

Pretty simple guys and girls the pitch of your smartphone or tablet dictates the pitch of the gimble. I find it a little pain in the butt to use as I am constantly moving my smartphone\RC following the Spark. But it does work as advertised.

This feature is suddenly disappear from my DJI go 4 app...
