Can you explain the deal with the canopy? The one I've played with at Buy Buy Baby has a canopy that's not attached at the bottom and every time I retract it, the bottom of the canopy kind of flops down almost to the bottom of the car seat. Is that how it's supposed to work or did they not attach something correctly? I noticed they got something wrong with their Mesa canopy too but I'd only know that since I have one at home.
