So say u made some mobile pages in /mobile folder 1.8 you can no long access theses on mobile version
I have not tryed htacess rewrite yet to see if it allows it
Every version release we lose more and more features
That a custom code modification
Please hire a dev to fix our script
In case of the static pages that you create via admin panel that has some html code, you can just duplicate the content and the title of the page and create the same page on mobile version
