I was able to apply a "dissolve" transition to every page in my script and it fades in and out perfectly fine! To replicate this, (I am on the latest build) go to the "transition plugin" and choose the "pages" tab. Select the dissolve transition and set the duration to 3 seconds or so. After this make sure the bubble next to "all pages in script" is selected and hit apply. It applies the transition to everything, in and out.
I hope this helps! If it doesn't for whatever reason, feel free to email us at firstname.lastname@example.org! Thanks.
