Play inicial y pantalla negra

Hi, Edu.

Thank you for reaching out!

If I understand correctly you're publishing from Replay 360 to Review 360. Is that what you mean by publishing to HTML?

Since your content likely contains video or audio, this article will explain why you see this behavior on modern browsers. 

If you can import your content (publish to a local video from Replay) into Storyline, one option to avoid the Play button is to insert a blank slide as your first slide and add a trigger to jump to the next slide when the timeline starts.

Keep in mind that this will also be browser-dependent, and while it might show the slide without the Play button, it might still require the user to click on the screen to hear the audio. 

In Storyline, you can also customize the black screen with the button by adding a cover photo. You can read more here.

I hope this helps!
