I have upgraded to Version: 2.6 and adjusted my setting but I am still having the same problem with mobile phones. But the problem has to do with the viewport meta tag If I remove it all is good,
With it I have a lot of problems. A) Customer gets cut off 1/2 second after answering chat. B) The departments show up in the Chat form.
Here are two test pages.
link removed with "viewport"
link removed without "viewport"
Again, no problem with desktops and tablets, just phones.
