My remote control for Mavic M ini will not turn on.  When I press power button (once, twice, whatever) it doesn't do a thing.  If I press and hold the power button for 5+ seconds, four lights come on and stay on for a couple seconds.  I can't fly my mini until this remote problem is straightened out.  It used to flash lights on first push of the button and then holding the button until the lights cycled would turn on the unit.  That doesn't do anything now.  

Hi rick, please full charge the remote controller, press once the power button, then again and hold on to turn the remote controller on. If the issue still persists, please start an online repair request on our official web and then send it back.
