Hello Rebecca,
I appreciate Ron's help here.
We are also monitoring another issue: audio continues to play after opening a tab when viewing a published Storyline output. Using the latest version, I tested this in a new Storyline course and confirmed the behavior. After switching to a new tab, the audio played, but the seekbar stopped as expected. Here's a link to my published Review 360 project if you want to test it.
I have linked this discussion to the audio bug so that you'll be notified once this issue is resolved. In the meantime, you can consider downgrading to Storyline 360, Build 3.87.32265.0, where the bug does not happen. Here's how to downgrade to a lower version.
Please don't hesitate to reach out if you have additional questions.
