Hello @martabruna,
We apologize for the delay in our response. We’re not sure what the issue is. Does the same problem occur in the Elementor editor as well? We’re also curious about the Slide to Show setting for your mobile devices. We recommend displaying only 1 or 2 slides on mobile devices due to their narrow width. The width is calculated using percentages, so if you display too many slides, they may appear hidden because they don’t have enough space to share the width (resulting in a height of 0). For more details, please refer to the image below.

We will await your further updates.
Thank You
Hello
Thank you very much for the quick response.
As you stated the problem was the “Slide to show” setting for mobile devices. Modifying this parameter solved the problem.
Thank you very much for your help.
You’re welcome @martabruna!
We’re glad to know that 🙂
If you have any other questions or issues in the future, feel free to create a new topic.
Thank you and have a great day!
