"No slides found" in presentation

[simonmeggle]

Hello,

I try claper for the first time, created and activated a survey.
When I start the presentation, I only get a black new window.
In the browser console I see

No slides found in ‹div class=" text-center" id="slider"> </div>

Do I have to add "slides" additionally?

If you haven't imported a presentation, when you start it you will only see interactions, such as messages and polls. Make sure you select these in the settings, otherwise you will only see a black screen.
