I have downloaded a Binary FBX file from Mixamo. When I open the animation in 3D Viewer, it plays normally, but I can't get the animation to play in Blender 2.9. I can't find any keyframes at all when I select the armature. I exported the video with skin at 24 frames per second, then 30. I can't make it work in 2.8 or 2.9. Do you know any good fixes for this problem?
