Googler Says You Can Ignore Mobile Usability Issue Notices If You Pass Live Test
https://www.seroundtable.comGoogle’s John Mueller said that if your page passes the live mobile usability test – that means you can ignore the Search Console notices of “new mobile usability issues detected for site.” So as long as you pass the live mobile friendly test, you are good to go.
John also mentioned that this is most likely because some CSS did not load that one time when they check for mobile friendliness.
