I have the latest iPad Pro. I purchased a usb hub that plugs into my charging port…BUT…(theres always a but), because of the case I have protecting my iPad, I need an extension cable that will go into my charging port and allow me to plug the hub into the other end of the cable…I’ve looked and it’s very confusing to decide what I should get. I already ordered one, and, of course, was wrong. Any help would be greatly appreciated.
