It now appears at most once, about 4 seconds after your third finished “Capture 5 s” result since this update. • It only appears if you have not touched the screen or left the app since that result, no capture is running and no automatic full-screen ad was shown in the last 30 seconds; otherwise it waits for a later capture. • “Review” in the menu is unchanged.
