"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.)."
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)
thumbnail is ok (cover or from <meta>). description is ok.
