The error: Content mismatch: Missing embedded video
The AMP-link post: Social Media Isn’t Social Any Longer (But It Used To Be)
As far as I can see, there’s nothing wrong. Both the YouTube title link and the YouTube video are correct — and the YouTube video is embedded and plays.
I checked all the HTML, submitted it as a corrected, and for the second time it’s telling me it’s wrong.
Does anyone have any idea?
