Issue Attempts to tween two or more instances of an animated symbol produce undesirable results.
Reason Animated symbols are not designed to be tweened. Their animation properties are set when they are created or altered in the Object panel. Although it is possible to tween them, unusual results will occur. Tweening should be reserved for graphic symbols. When the frames are displayed in rapid succession in a browser, the animated GIF often gives the illusion of continuous movement or change.
