I noticed a difference in how I was placing things in my game and how they were showing up in the preview so I changed the setting to "Fit to height" and it moved things so it would fit correctly - obviously, but the buttons and such were out of place from where they were originally set. I'm wondering if I should adjust my buttons so they look correct in the preview or where I'm actually building my game. I just don't want it to be all messed up when it comes time to actually putting it on the app store. Thanks guys!
buttons with stick to edge ticked will stick to the edge of the screen when it is resized, but left unticked, they will stay right where you put them no matter the screen, so have a play with that on the different screen sizes in preview and even try fit to width and see if that's worse or better, i often get confused between the two
