Hey @Andre17 .

Thanks for reaching out.

I appreciate that you have provided your online store URL as that is very helpful! I went to your online store using my mobile device to see that the menu icon is not opening the navigation menu as intended. Just to gather some additional context, did you happen to make any custom coding coding to the theme?

While I was looking into the store, I did notice that the Atlantic theme is designed and supported by Pixel Union. With that being said, since it was not developed by Shopify we are a bit unfamiliar with the style of coding that is being used within the theme. I would recommend reaching out to the developers of the theme as they are in the best position to provide further assistance and insight to fixing the menu icon.

Looking forward to your response, let me know if you have any questions.

Hi Ollie,

You right, I supposed to contact Pixel Union team as the Atlantic theme not from Shopify. However, I have contacted them and the problem was my theme was outdated, and the issue was resolved once i have updated the theme. Thank you so much for replying!
