The 'After time delay (s)' action allows an Aura creator to define a period of time before a given Overlay appears. This can be an effective way of providing users the opportunity to click-thru to a web page, but not until they have watched a given portion of a video, as can be seen in the example below:
Once the 'after time delay' action has been selected inside the Studio, an additional box will appear that allows you to define the length of the delay in seconds.
Time delay is measured from the moment the host Overlay starts, and if stopped and started again, will re occur. Pausing the host overlay will NOT pause the countdown of this event.
