Greeting Message

Hello, I’m having an issue with my greeting message.

When viewing the site on tablet/mobile the greeting message pops up and when I’ve selected to close, it keeps popping open afterwards. Is there a setting to stop this and also is there is some code I can use to get rid of the greeting message all together that would be great, especially for tablet and mobile-only!!

Thank you in advance.
