Hi, I understand that when you visit some webpages on the desktop, that their mobile sites are showing up. Does this happen after you clear the cache? Device meta data is stored sometime on some sites in order to cache the correct version of the web page. If this is happening on the android device click on the three dot menu > And uncheck "Request Desktop Site" and reload the page. To correct this on desktop if clearing the cache does not work, go to about:permissions and search for the two sites. Click on "Forget this site"
