When opening the app, a loading screen will appear briefly. To change the default image click the Browse button below 'Portrait Image' to launch the Media Library and upload your logo. Drag and drop it onto the placeholder to use it as the loading screen for smartphones (and tablets held in an upright position).
Repeat these steps to create a landscape loading screen for tablets held horizontally.
Tip: Ideal Image size for the Loading Screen is 1280px x 720px for portrait and 720px x 1280px for landscape.
