 * Hi there,
 * Thanks for contacting us and hope you are doing well and having a great day.
 * To rule out the possibility of a plugin or theme conflict, please deactivate 
   all your plugins (besides Elementor ). If it solves the issue reactivate them
   one by one to find the culprit. If it didn’t help, switch your theme (temporarily)
   to a default WP theme such as Twenty Nineteen and see if it makes any difference.
 * Also, this could happen due to our Elementor performance experiments you can 
   try to deactivate them. To deactivate them you can go to Elementor > settings
   > features
 * Performance features currently in the experimental stage are:
    - Element Caching – Elements caching reduces loading times by serving up a copy
      of an element instead of rendering it fresh every time the page is loaded.
      When active, Elementor will determine which elements can benefit from static
      loading – but you can override this.
    - [Inline Font Icons](https://elementor.com/help/inline-font-awesome/) – This
      experiment renders icons as SVGs without loading the Font-Awesome and eicons
      libraries. Since SVGs are vector-based images which are rendered using the
      browser’s engine, they do not increase server requests which improves performance
 * I am looking forward to hearing back from you soon.
 * Kind regards,
