I got a warning:
"New reason preventing your videos from being indexed
Search Console has identified that some videos on your site are not being indexed due to the following new reason:
No thumbnail URL provided
If this reason is not intentional, we recommend that you fix it in order to get affected videos indexed and appearing on Google."
It's strange that I don't have any videos on the website at all, so I don't know what kind of videos they are talking about, unless they mean maybe sporadic videos from advertisers that are automatically placed via Adsense.
