p4 pro plus

Dear fellow P4 pro/+ pilots... Is anyone having problems getting any video footage recorded? I get my drone in the air, hit record, little to nothing happens then after an indicated 3 seconds, stops recording.... Is there a setting/ configuration I am missing, are these drones very particular...

First flight today with a shiny new P4Pro, no problems, shot some footage, landed, changed battery. Now the gimbal pitches from max to min continuously. I cannot seem to find any documentation about this problem on this or other forums. Clearly the camera is useless at the moment ...

I am thinking about upgraded the the Phantom 4 Pro Plus and haven't found any backpacks or cases that say they are compatible. Has anyone found anything that works yet?
