Here´s the most basic example of why the movie interactivity doesn´t work fully in Edge.
In the project below is nothing but an imported 3D animated movie clip (which works), and a button telling the movie to play (which works too).
At the 3,5 mark there´s a trigger telling the movie to pause. It doesn´t, it keeps on running. I´ve tried using "stop all" and multiple other actions, by themselves or in combinations. The movie doesn´t pause. I have managed to make it pause at different intervals, but it was so cumbersome I can´t use it in my work as a graphic news designer. Edge constantly crashes too.
I hope this problem will be adressed in the next update. I bought Edge to add interactivity to animations done in 3D programs, and for now I can´t use Edge for that. Unless I have missed some crucial feature.
