there's no date

This is the wrong author.

The text at the bottom should also be included, as it is content from the article.

Slideshow appears to not be functioning, not even on ctrl+click, so I cannot check if the videos are supported - I assume they're not, since missing a video src

Sorry for sending in another issue for the same problem, I wasn't clear enough before:
Videos that cannot be embedded need to be @unsupported according to the rules: https://instantview.telegram.org/checklist#2-3-pages-featuring-content-unsupported-in-the-iv-format

The videos aren't supported, but if I use the @unsupported function, nearly no page can be viewed because nearly all pages have a video embedded because "heude.de" is a TV show.

As already mentioned in #3:
The videos aren't supported, but if I use the @unsupported function, almost no page can be viewed because nearly every page has a video embedded. In my opinion it's better to have an IV with the video summary and the preview image instead if no IV. Would be nice if the admin could help out with the problem :D

There are videos which are not supported. Therefore, you should use the @unsupported function.
