On the P4, which I've owned for some five days now (!), directly above the camera is a flat circular face at the bottom of a vertical rotating component of the gimbal. This appears to have a piece of self-adhesive protective film applied to it, with a little pull-off tag protruding from the edge. Nowhere, however, can I find any reference to it, so I am unsure whether to remove it or leave it on. I can't actually see any obvious reason why it is there in the first place. Any guidance please anyone, whether or not to remove it? Thanks, Tony.
Addendum: I've just spotted a couple of photos which show the thing I'm trying to describe - complete with the little orange 'pull-off' tab I mentioned. The photos are from an eBay listing. Any thoughts, anyone?
