 * yes please? is from your last update with the API all my sites get the error.
   
   in tag manager. manual code. and even with your plugin.
 * why? why is causing so many problems?
    code not compile, and even cause SEO issues
   with google search console crawler.
 * “Googlebot”
    read the facebook.com/tr (the icon) and rank the icon in the search
   result! the robot.txt cant passes it because is not my URL. is external URL you
   put in the pixel and you take all the SEO from my websites.
