@DBear, @JimScott Thanks Guys.
My bro has a android tablet and phone. With Chrome 66. Did not think to ask his OS. version.
Will check with him and see what it is.
Turns out his tablet is on version 4x. So that expalins that …
The Phone is v7. And somehow this morning he can see the chat box on his phone. I have not changed anything and was on 2hr call to him trying different things to get it to work on his phone and Tablet.
News just in, he has just texted and says he forgot he needed to test in Mobile Chrome and not the default browser. what ever that is. And it still does not show in his Mobile Chrome browser.
So I am at a loss as what is going on and if there will be others or cannot see the chat box.!!??
