Gravity only effecting sprite with Rigidbody, not Rigidbody 2D

I have a simple sprite (with no animator) that simply refuses to fall with the Rigidbody 2D component. If I give it the Rigidbody component instead it falls perfectly fine. Pretty sure I have the correct settings for Rigidbody 2D as well:
Dynamic
Simulated
Gravity scale: 1
No constraints checked
Starts awake

Any thoughts why Rigidbody 2D ins’t behaving with a simple sprite? Feel free to ask for more info if I haven’t provided sufficient detail.

Solved it. It’s a collaborative project and another member set the Physics 2D project settings ‘Y’ value to 0 :stuck_out_tongue:
