To move an app, just highlight it, then hit the asterisk "*" button. Choose MOVE, and then move it to where you want it, then hit OK to drop it there.
Re: moving position on screen
I suspect this is on a Roku TV. The tiles for individual input ports previously could be shown as separate tiles on the home screen for easy direct access. One can label them to indicate what is attached (such as the poster's xbox). For those receiving the update, the input tiles now have been grouped under one single "Inputs" tile that one has to click then choose from a menu. NOBODY seems to like this change and many have voiced a desire to move individual sources back to their own tiles on the home screen.
