Went to fly my Mavic Pro today and when I was on location I notice the D-Pad button was missing. I always keep the button protector on when not in use and have never drop the controller. It looks like I will either need to send it in for repair or try to replace the button myself. Has anyone else experienced this? Is it something that you can do yourself? I have another Mavic Pro, but that controller doesn’t have the Ilite range extender. Arghhhhhhh
