Hi. I just received my Inspire Pro today, but I cant seem to get the gimbal to attach to the aircraft. The locking mechanism only seems to turn half of the way and then no further. I dont want to force it. I think I know the issue. The rubber seal on the top mounting part of the zenmuse is loose and kind of sticking up slightly. I think this is preventing the mechanism from fully locking. Is this rubber seal fully necessary? As far as I can see that is all that's wrong? What do you think?
