For those of you having trouble with the app buttons not matching the buttons on the case, make sure you have selected the correct housing type in the menu! It took me a while to figure it out because I was not prompted to do that when I first booted up the app. Once you select the correct casing, the app buttons change position and match up well! Hope this helps everyone!!
