I just learned that some animation transfer addons for Mixamo to Rigify require precision. This time I was successful. I tried a character without a rig and rigged it with the Mixamo auto rig. So next time I will delete my Rigify rig send it through the auto rig to grabs some animations. If you don’t do so it will most likely cause horrifying results.
But importing directly from Mixamo via FBX gotta watch out or you’ll end up with 100m+ tall characters.
