Youtube Notification stating: "Starting in November, we're simplifying the choices for ad formats that show before or after your video to improve creator revenue. In November, we’re removing the individual ad choices for pre-roll, post-roll, skippable, and non-skippable ads. Going forward, when you turn on ads for new long-form videos, we'll show your viewers pre-roll, post-roll, skippable, or non-skippable ads when appropriate. This change makes the recommended best practice to turn on all ad formats, the standard for everyone. Your choices for mid-roll ads are not changing. We will also retain your ad settings for existing long-form videos, unless you change the monetization settings."
