I got a rain cover with my Bugaboo Bee 5 pram but can’t work out how to fit it! It looks different to the ones in the demo videos - mine has a grey section at one end with the Bugaboo logo on, has popper style buttons along some of the edge and there’s no flap on it. Part of the cover is elasticated too. I have the buggy in parent-facing mode at the moment. Can anyone advise?
