    Hello,

    I’m having an issue with the Cumulative Layout Shift metric in Google PageSpeed Insights. On desktop the score is .027 which is great. However, on mobile it’s .369. I have noticed that on mobile when I click Menu the entire page shifts down as the menu items are displayed. Can this be the cause of the relatively high CLS score on mobile? If yes, how do I fix it? Is there anything else on mobile that might be causing the high CLS?

    Thanks

    I made the following change which didn’t seem to help the CLS score.
    Layout > Sticky Navigation > Sticky Navigation = “Mobile only” WAS set to “Off”

    Hi there,

    I believe the issue is that your logo and menu toggle are too close together.

    What happens if you decrease the font size of the toggle or decrease the width of the logo?
