Google's mobile usability report within Google Webmaster Tools is currently running a two-week delay.
If you check out your report, you will see the last updated date was on January 13, 2015 - 11 days ago.
One webmaster has been working on fixing his issues but is trying to be patient to see if the changes are noticed by Google Webmaster Tools. He posted his concerns in the Google Webmaster Help forums stating:
I have been looking at our mobile usability reports on Webmaster Tools to determine what issues need to be fixed.The reports have been updating almost every 3 days with the latest pages found with issues but the last update was on January 12. Since then no more pages have been reported but Google keeps crawling the site every day. Is this OK?
This should not concern anyone, it is not uncommon for those reports to have delays.
