This thread is resolved. Here is a description of the problem and solution.

Problem:
The client was experiencing issues with video embedding on their multilingual site using WPML. The videos were not displaying correctly in the German version, and there were outdated translations on the page certificate despite attempts to update them through the WPML dashboard.
Solution:
We investigated the issues and identified that the Perfmatters plugin, which is not officially compatible with WPML, was causing the video embedding problem. Disabling the Perfmatters plugin resolved the issue, allowing videos to display correctly in both languages. For the outdated translations, we recommend re-translating the content manually if automatic updates through the WPML dashboard do not reflect the changes.
For caching solutions that are compatible with WPML, we suggest checking the list of officially supported cache plugins here: https://wpml.org/plugin-functionality/caching/

Please note that this solution might be outdated or not applicable to your specific case. If the issue persists, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If necessary, please open a new support ticket for further assistance at WPML support forum.

Dear Drazen,

thank you very much for your answers.
Okay, let's tackle the issues based on which website they are.

Starting with the points 1-7
That is on hidden link.

Point 1-3 are clear, thank you for explaining.
4 is actually a point for map.pfotenpiloten.org/up so lets to that later.

5. Page certificate - outdated translation
I clicked on translating it again automatically in the WPML dashboard but unfortunately the text in the side by side editor is still outdated. How do I re-translate correctly?

6. Front page with multiple issues
I made you a video, I think it is easier for you to take a look.

And if needed, I can request a WP staging login for you from our team.

7. About us page - video
Also a short video that you can see it. With a great demonstration effect, normally the videos works on the english version. But my guess is, we have to break the connection to use a different embed code for the german video - correct?

Hello,

thanks I tried to check the video issue, but I do not see German version probably hidden.

Anyways best would be to provide access to staging site, if possible and I will have a look to what might be the issue.

Regards,
Drazen

Hello,

Thanks.

I checked your setup and the issue appears to be caused by the Perfmatters plugin. When I disable it, everything works correctly on both languages.

Video for reference:

This plugin is not officially compatible with WPML, so issues like this can occur. We have tried to collaborate with the author in the past.

I recommend contacting the plugin author to report this, or alternatively using officially compatible plugins.

Best regards,
Dražen

Thank you. I will discuss it with the team and let you know.

Can you recommend an officially compatible plugin that does the same (delayed loading)?
