    For me, when I create a new button, it is not aligning with the previous button. Did you do something previously for that or is there something I am missing?

    I know absolutely nothing about app development. I started here because I wanted to make an app. The problem I'm having is I made it to where you start moving the button and when I tried the same it would just move back to it original location. I'm not sure what I'm missing. I did everything you do up to that point.
