I just received a replacement drone from DJI for my crashed Mavic Pro. It came wrapped in bubble wrap so I assume it's a refurb. First off, when I turn the drone on, the gimbal makes a few clicking noises while going through the startup process. My old one didn't do that. The new one also has what looks like a belt protruding from the back of the gimbal in a loop. I never noticed this on my old one. Lastly, the new drone isn't showing up on my DJI app on my Ipad or Smartphone. I don't recall the activation procedures for my old one but nothing is alerting me to do anything on either of my devices. I've tried searching on here but I'm getting nowhere.
