How on earth do I reconnect the P9 ribbon cable?

I have tried it a million times! I cannot for the life of me figure out how the ribbon cable goes back into the connector on the motherboard! What am I missing? All of the YouTube videos I have watched have effortlessly slid it into place, but it almost feels like a wall has been erected in the slot the cable is supposed to enter into! Has anyone experienced anything similar? Any advice on what I am missing?

( The P9 is either for the camera or the speakers if that helps to identify it)
