Hi. I have a weird behavior. It havent been like this before. but it happens now and it ruins the whole experience.

on a mobile devices, live chat opens with welcome messages, but that pop up does not have a [X] close button which normally I can see on a desktop.

How can I get the [X] close button back on a mobile browsers?
