Aww...OK.
I don't get knotting with twists or braids, but I don't use products. Not sure if that has anything to do with it. I also redo my braids as they need it so they never get a chance to knot up at the base. Also making sure not to use conditioner near the base and not applying products means that there's no residue build up that could create a knot at the base.
There are others who use products and also have good success with C&G. Hopefully someone can help you figure out what change you need to make to enjoy your braids. Otherwise, maybe practice will make perfect. Like when you braid, do you make sure not to mix hair from each of the 3 strands? In other words, once you start braiding, keep strands in their own 1/3 section all the way to the end. Smoothing as you braid so that hairs don't mix in where they don't belong also helps. And when you undo, I hope you don't use a comb but rather feel with your fingers
like I do.
