What is on the bottom left of an Amp if y Pre-rollvideo?

The correct answer is "A time countdown." When a pre-roll video ad plays on Amplify, a small countdown timer appears in the bottom left corner of the video player. This timer indicates how much time remains before the main content begins, providing transparency to the viewer. Your handle's logo is typically displayed in the top left or right corner, not the bottom left. A publisher thumbnail might appear as a static image before the video starts or as part of related content suggestions, but not as an overlay during the pre-roll itself.
