I have the Mavic pro. I seem to be having some issues recently. I have gotten a no gps with atti mode. It goes into opti mode. It will take off and hover my 50 feet and says it has reached maximum altitude. I bring it down and land it then try again and goes higher. I have the red indicator by satellites. Then I had a downward sensor failure at landing. Strange behavior. I get a RTH update while airborne. I’ve always flown from my rive way. No problems until about a week ago. Any help would be great.
