My Mav3 Pro flew into a river. I used Flyaway to order a replacement. They sent the replacement with a DJI baseball cap, then DJI called to tell me they were sending an email with a coupon for a battery. I figured $10 off but..it was for a FREE...
Because of the limitations placed on the drone while in that mode. The Mavic 4 does not allow gain and expo changes in Cine Mode. Use normal mode and adjust there.
