I'm having an issue where pages are coming up with "non mobile friendly" warnings in search.
I do mobile tests on those pages and they pass. I do fetch as google and they look as mobile as can be. I do tests on chrome with user agents and it goes to the mobile version.
I will clearly note - the site does "dynamic serving" based on user agent/screen size.
When I had this problem last year as well. It lasted for a few days and only with our most recent content and then resolved itself on it's own.
One webmaster told me this is common with dynamic sites, that sometimes the bot gets confused and sorts it out?
We are using separate css files for each dynamic version, so I know that's not the issue.
Our articles for the last few hours are NOT coming up without those webmaster warnings when I see them in search - but 95% of the articles posted in the prior 2-3 days before those articles in question, they are being tagged as non-friendly (for my eyes only in search). We have over 110K articles and everything prior to today appears fine.
Hoping someone can have more input? Is this some issue that comes and goes with dynamic serving?
Did Google do some sort of update that might be causing this? Because all of the affected pages are passing every Google related test, so I'm pretty much grasping at straws.
