Google Mobile-Friendly Test
Working to beat a couple of Rocketthemed Joomla sites into good enough shape to pass the Google Mobile-Friendly Test and found the main thing I had to do was adjust my robots.txt files to unblock (putting a # at the beginning of the line) the following Items.
cache
components
images
libraries
media
modules
plugins
templates
I hope someone finds that useful
