Strange Camera behavior

Hi all,
I’ve been developing our first Verge3D project for a couple of weeks now.
I still can’t understand this weird camera behavior, Tween Camera to object works fine but the rotation is not translated and corrects itself in the last frame.

Here is the video: https://www.dropbox.com/s/8199bsi7dlc3bou/2019-10-14%2011-06-07.mp4?dl=0

One more question: is there a way to override default controls and assign mine? We are using touch displays and it needs 2 fingers to move the camera and single touch to rotate around the target, I need to swap that behavior.
