Could you try to make the canGoThrough platform's collider2D very thin (or use an edge collider)?

I would try checking if the players velocity.y > 0. then make it's collider a trigger. In C#, it could be one line in the players update. although you might only want to check when the player is not grounded.

 gameObject.collider2D.isTrigger = (gameObject.rigidbody.velocity.y > 0) ? true : false ;
