 * Hi Frank,
 * really amazing plugin. I’m facing one minor issue:
    When loading the mobile version
   of my page, the content of the menu flashes for a break of a second. I suspect
   that I have to exclude this somehow from CSS generation or either from defered
   loading. Any idea?
 * Thanks for your help!
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fmobile-menu-flashed-when-loading%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Morning Andy;
    Can you try adding
 *     ```
       #mobile_menu1{display:none;}
       ```
   
 * in Autoptimize -> “Critical CSS” -> “add CSS to all rules” ?
 * hope this helps,
    frank
