I don’t see the Animation option when I go to Windows, all I see is the timeline option. :/ Try looking in Google for the mean time. I’m going to try to figure out myself as well and see if there even is an animation window.
you go to the little menu on the side, like the one that says to convert frames to layers and stuff that usual menu, and go to convert < window animation something like that, and do the menue again, and then go to animation < frame animation.
Windows > Workspace > Motion
That’s how I get the animation thing to pop up.
It’s just automatically there, just change the thing from timeline to frames where that little icon is. :)
