I've had my Phantom Vision 2+ for about a week. The camera was working fine, but yesterday it stopped tilting. The DJI app shows a camera view, but when I try to tilt, the bar on the right side of the screen turns red - apparently indicating it has an error. It also won't tilt with the dial on the controller. I can record but not tilt. It is locked in the front facing 90 degree position. Any ideas on why? I'm hoping I won't have to send it back for repairs already.
