Hello guys. As the title says I'm struggling to import a simple animation for this slime character. I'm using Unity 6.4 and Maya 25.

The problem is that no matter how I export the fbx (model + rig + animation) the animation does not play properly. In the video you can check my full settings in Maya and Unity. I followed many tutorial and tried different things but nothing seems to work. It's like the spine joints works, the eyes works, but the other joints don't and it is not making the slime moving like I keyed in maya.  
Extra info:  
All joints have 1,1,1 scale, no funny transformation, no bs, no extra skin layers. Model has no textures or UV (not that it matters). 

Also as a extra test I try to simple create a sphere in Maya and made one joint, skin it and move it left to right and it works. I then try to make a chain of three joints instead and curve it and move it around but it doesnt seem to move properly so I'm guessing there is an issue with multiple joints hierarchy? I'm out of ideas, I wouldn't post here otherwise lol. 

Any help will be much appreciated. 

  
One more thing, the rig and the model is fully functional in Maya and UE5, so could be Unity's fault? Help.
