Have you tried using "Go to next/previous layout"?
If that doesn't work, try this method: Use a variable or dictionary key to store the layout name.
Upon entering the current level (such as level 3), on start of layout, set the variable to "LayoutName", without the quotes. Then when you run your ad, at the end where it's supposed to return the player, add a "Go to layout (by name)" and use the variable you made in place of a direct name.
Hey
Thanks for the quick response. I don't think that will work because the ads are displayed in middle of the game so if I reload that level again the player has to start from start which will not work.
