Yes, you have link on T channel, date, article and so on. But your template left don't have Name of section(this site has 4 section, with it will be more comfortable), and your removed "footer" info with T and Viber links.

Missed the date.

Wrong date and author

no captions under the photo

Wrong time: IV time must be in UTC format, when on this template it in +2 GMT

"If a short description exists in the source, it must be used for the link preview (OpenGraph descriptions, lead sections, etc.)."

https://instantview.telegram.org/checklist#3-2-link-preview

This page have lead section (https://instantview.telegram.org/contest/bykvu.com/template2/issue4/), but it is not used as a description. Instead of it it uses all text (untill Telegam cut it)

I think that admin did a mistake, when declined my issue:
https://instantview.telegram.org/contest/bykvu.com/template2/issue5/

As you can check, <div> with selected text has special @class="itemIntroText" and on every page of bykvu.com lead highlighted by dividing lines, and has a different look from article text

But, as you can see, description for that page has text "Ролик..." which is contained NOT IN LEAD SECTION

And again, from checklist:
"If a short description exists in the source, it must be used for the link preview (OpenGraph descriptions, lead sections, etc.)."

"If a short description exists...[]...IT MUST BE USED" - but instead of it uses not a SHORT DESCRIPTION, but all text in the article

"3.2. Link preview
• Thumbnail for link preview must be shown if a suitable image or document exists in the source.
• If a short description exists in the source, it must be used for the link preview (OpenGraph descriptions, lead sections, etc.)."

https://instantview.telegram.org/checklist#3-2-link-preview

As you can see:
1) Wrong thumbnail. Just check my template
2) Wrong description. There are lead paragraph (bold text at start) which can be used as a description, as my template do. This template uses all text to generate a description ("Ролик..." at the end is a part of 2nd paragraph, which is not in lead section)

Wrong thumbnail

Wrong thumbnail on link preview. It uses even not a cover image, but image which is under 5 paragraphs in text (https://bykvu.com/media/k2/items/cache/5bf55fa8a4a0ff4975a416d28bf51766_L.jpg?t=1467915893)
