Pages With App Interstitials Now Lose Mobile Friendly Ranking Boost

Pages that serve app interstitials are now losing the mobile-friendly tag as well as their ranking boost. The easiest fix to app interstitials is changing it to an app banner instead. People have been testing ways to get around the change by leaving a sliver at the bottom of the page so that the app interstitial still exists but is not recognized as so by Google's crawlers. They are working on finding a way to catch all of these.
