I am using someone else's google slide presentation in my vMix production. I am pulling the Google Slide presentation up as a website. Then I am clicking "Start slideshow" using my mouse inside the input window. It goes full screen. All good. But then I want the slideshow to auto advance, (which the orginial file is set to auto advance but for some reason it is not in vMix. So my manual solution is to mouse click in the input window to advance the slide. That works but I need it to be automated and advance every 7 seconds. How do I do that? I have tried to figure it out and can not.
