Our Website Favicon has disappeared from the SERP & Google Search Console

Our website www.infostor.com 

From last week our website Favicon disappeared from the SERP & Google Search Console. 

Following the Favicon guideline pages we done some changes and added Favicon ICO files in our root folder and still the Favicon is not appearing 

We also found a Popular site socialmediatoday.com also Favicon is missing, is this a technical glitch from Google ? 

Please help if anyone knows a fix

Thanks
