The delay function in OptimizePress allows you to delay an item or element (whether it is a feature box, optin form or call to action button) from showing for a set amount of time after the page is loaded. It is important to note that this timer starts from when the page is loaded - not from when a video is played on the page or any other timer.
To setup the delay timer , when you add an element to the page you will see when you hover over it a set of icons in the top right - one of them looks like a cog or gear.
