Reolink E1 stuck in down position

[user_904519689056419_904519689056419]

I've had my web cam since the New Year. The camera gets stuck in the "down" position. For example, it follows a bird around the garden, but if the camera has to move down, it gets stuck there, and I have to push it back and reboot. Can I lubricate it somewhere to help?

@user_904519689056419_904519689056419 Will calibration move the camera? I guess you have the auto return timer enabled.

@joseph_1979 I tried restarting the camera, and one of the gimbals moves, but not the stuck camera.
I notice there are horizontal right/left limits that can be set, but there does not appear to be any for vertical top/bottom limits.
