 * Hello,
 * When having Autoptimize enabled, the mobile dropdown menu does not work. When
   disabled it works just fine. I added this wp-content/themes/nss/js/navigation.
   js to exclude from Javascript and CSS, cleared cache and still does not work.
   Any suggestions?

 * maybe before trying to exclude stuff try simply disabling CSS or JS optimization
   to see which one is impacting the menu for starters. based on that we can see
   what the next step(s) should be 🙂

 * So it is Javascript that is the issue. CSS is fine

 * OK, so when JS optimization is active, what JavaScript errors do you see on the
   browser console?

 * A page or script is accessing at least one of navigator.userAgent, navigator.
   appVersion, and navigator.platform. Starting in Chrome 101, the amount of information
   available in the User Agent string will be reduced.
    To fix this issue, replace
   the usage of navigator.userAgent, navigator.appVersion, and navigator.platform
   with feature detection, progressive enhancement, or migrate to navigator.userAgentData.

 * hmm, afraid that doesn’t help us (not relevant to the issue). can you try adding
   just `wp-content/themes` or `wp-content/plugins` to the comma-separated JS optimization
   exclusion list to see if that allows us to get closer to finding the culprit?
