How do you go about selling a DJI drone with Refresh?

If I delete it from my DJI account / profile will the DJI Refresh still work when the new owner adds it to theirs? Will the flyaway coverage still be valid?

I’ve read the T&Cs but I can’t make head nor tail of them, it goes on about binding controllers / accounts and unbounding them but I don’t know what it’s on about!

The Care Refresh is bound to the drones serial number.
