Hello Korey,
I'm happy to help! Storyline blocks play automatically by design on desktops and laptops, but browser restrictions can prevent this when the first slide has audio or a video. You can prevent Storyline blocks from autoplaying using the following methods.
If your Storyline block doesn't have audio or a video on the first slide, create a custom play button to start the course. You can also use a dialog layer to pause your slide. If your Storyline block has audio or starts with a video, the built-in play button will show in some browsers. If the play button does not appear, insert a blank slide with a play button as your first slide.
Check out the article below for detailed steps on how to achieve these.
Please don't hesitate to reach out if you have additional questions.
