Noticed tonight that starting any pano shot (180, sphere, vertical), the round photo button will change to the "stop" square, the gimbal will jerk itself centered, and the progress will sit at 0% forever. Videos and normal photos work fine.

I know I took some pano shots when the drone arrived a few weeks ago, and I don't think I changed anything that would prevent them from working now. But is there anything simple I should check?
