linking to remote controller

I received my Mavic Pro back from warranty work and I'm having trouble linking my RC to the aircraft...and the DJI GO app no longer contains the DJI Mavic Pro as a device choice. Anyone else having this issue?

Where do you look to find what you named your quad? Mine just came back from a repair and I have to Link my RC, and one of the first questions is "...what's the name of your device....and I can't remember what I named my new Mavic. Thanks is advance.
