blender rigged animation plays, but scaling of the model does not.

I have a model with a rigged animation as well as a scaling animation of the entire model, both of these occur at the same time and it appears perfect in blender. When I import it into unity only the rig animation plays. I do have every single vertex assigned to a bone as well, as I know not doing that can cause issues.

If anyone knows why this might be thank you in advance!
