Thanks and i think ik why it wasn't working it was because of i was uploading the file in the old editor instead of the new one. And i figured it out

Oh idk that

But thanks

Ok

So if u want to upload a file on the new editor u go to the new editor you go to the gear icon you press upload project then you find the file u want to upload and then it will show project will clear current animation then u press ok then the file is there. But if it doesn't work you can tell me and i can find another way to upload it.
