Bag Doesn't Light Up!

I was so excited to get my Jem bag today. It's absolutely beautiful. I actually said "wow" when I unboxed it and saw the glittery finish. But it won't light up! 😔 Has anyone else had this issue? I've contacted customer service and I'm just hoping I can get a replacement before they sell out. It's not like Loungefly is known for their outstanding customer service.
