Get Viewport Size and 0.2 Delay

When my game starts up, I calculate what the OrthoWidth for my game should be based on the Viewport size, similar to Tappy Chicken, and like Tappy chicken I need to put a 0.2 delay. However, I can’t figure out how I can make the transition smooth. When the game first starts off, it just has the camera really zoomed in before it adjusts the Orthowidth accordingly. How can I make this smoother, so the first scene the player sees is finished setup?
