Youtube Monetization Advertising
When you decide to monetize your videos with Ads from Youtube, it seems that there are many types of Ads formats for you to choose.
However, the theme only supports Overlay Ads at this time and please note that you need to turn OFF the AUTO PLAY to ensure this Banner ad can display. For more details of this Ad format, please check here
NOTE: The Youtube Overlay Ads are ONLY available for Desktop, not Mobile as you can see in the guide of Youtube
