The remote controller for my Bt300 glasses will not turn on. It’s the first time it has not done so. Has anyone come across this issue and know of a way to get it going? Mine have had thousands of hours of use with an Air, Mavic Pro, Phantom 4 pro and Mavic 2. They really have lasted a long time. But I would rather not buy a new pair given the hope that there will be software available for the new glasses soon. Is there an easy fix or repair process?
