Hi there,
Welcome to SeaTheme forum.
I have checked your website, and it seems that the issue may be due to the small size of the menu icon. Please try increasing the size of the menu icon to identify the cause initially. If the problem persists, could you provide me with some more detailed instructions? (You can record a video, upload it to a third-party platform like Dropbox, and then paste the video link.)
Regards!
