Yes, your WP Facebook Comments plugin works perfectly on Desktop and AMP (Accelerated Mobile Pages) Mobile. The problem is that with bbPress-for-AMP plugin installed to make my forum run on AMP, Google Search Console throws the error “The extension ‘amp-facebook-comments’ was found on this page, but is unused. Please remove this extension.”
I cannot turn WP Facebook Comments off for just the forum. So, therefore, must turn WP Facebook Comments off for the whole site including 800 article posts that have nothing to do with the forum. If I were to turn bbPress-for-AMP plugin off I wouldn’t get the Google Search Console error.
