I'm having trouble creating a presentation which consisgts of 12 animated symbols spaced at labelled intervals along the timeline. When the playhead reaches a label, the main timeline stops and the symbol should play.
But it seams sometimes the symbol has already begun to play and it's half finished by the time the timeline has reached it.
My question: What is it that tells these symbols to play? Do they play when invisible, or do they wait until the timeline makes them visible? Do they start to play at that point because the autoplay checkbox inside the symbol is turned on?
