As it is a brand new zip the above should solve the problem

So in a good good faith effort used a lubricant i have on hand for guitars

Before any further action is taken to make a zipper slide easier and more smoothly you can rub several household items directly on the zipper such as a graphite pencil candle wax or a bar of soap to lubricate contact points and prevent the zipper from getting stuck

Immediately got what seemed to be an auto response i am really sorry to hear that
