Make sure both rigidbodies are kinetic and the colliders are not triggers. Thats what worked for me.

You can try

// All you have to do is make the ball the child of the platform
// Add this to the player

// You might have to do OnCollisionStay
void OnCollisionEnter(Collision col){
if(col.gameObject.tag == "Platform"){
gameObject.transform.parent = col.gameObject.transform;
//Disable any Components below this that you might need to do.
//Comp1
//Comp2
//Etc.
}
}

void OnCollisionExit(){
//De-Parent our ball from the platform
gameObject.transform.parent = null;
//Re-enable any components below this.
}

If this is correct and works for you, please mark this as correct so others will know.
Hope that helped.
