On Android, it appears as expected, with the original app still visible in the background and equal space on either side of the browser.
On iOS (iPad), all the space appears on the top and right side. The browser is flush with the bottom and left sides. The title bar appears across the entire top of the screen. And none of the original app is visible in the background (only solid black).
Am I doing something wrong? On iOS, is there a way to have the web browser appear on top of the original app (Centered) with the original app still visible around the edges, so it’s like a popup? As it is now, it appears like a separate app.
