Hi i just got an Air 2S with the RC-N1 and bought the DJI Tablet Holder to use with my ipad,, but i cant work out how to connect a Lanyard / Harness to the thing,, Can anyone please give me a clue??

Hello there GREEBO22. Good day and thank you for reaching out.  Kindly please post a photo of the setup that you have with your DJI RC-N1 Remote Controller with the Tablet Holder for us to be bale to see and can assist you. Thank you.

Hi DJI Stephen thanks for the tip, as I said the standard controller with the AIR 2s and the DJI tablet holder so here are the pics from the DJI
website

Take a look at the Mavmount.  I have the "Mavmount Scout" (with lanyard) that can hold my iPhone or up to a 7" wide tablet, and it is way more sturdy.  Yes expensive but well worth it.
