Animations (just like decals and meshes) have to go through moderation too. It seems like itβs the case here too. I say wait a bit before showing it to others or just recording the animation being played.
I know when I had animations published to my own account rather than a group that my friends and I were working in, the animations showed for me and not my friends. This could be the case for you as well? Make sure if you are working on a group game you save your animations to group assets or else it may have the same issue I faced.
