I just was given a City Mini Double by a friend, but she did not have the harness/straps anymore. So I called up City Mini and they actually mailed me replacement ones for $12…but I can not for the life of me figure out how they work! Anyone that has a city mini double, can you take a pic of how your straps are attached to the stroller? I feel like I am missing a piece because I just have one super long piece of fabric with two hooks for either side.
