Thanks. Now it works 🙂
Your last point is the solution!
It works better. However, there is still a small snippet of code below the video.
On the website I have shown the first video twice in both versions
https://www.suite-11.de/immobilienverkauf-ratgeber/
We use Divi as a page builder. I integrated the YouTube video with a code element and an iframe. For example:
<iframe width=”1920″ height=”1080″ src=”https://www.youtube.com/embed/D-d9PcyihuI” frameborder=”0″ allow=”accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture” allowfullscreen></iframe>
When I use the video element from the builder, the performance and pagespeed drop enormously.
