MarchieB:
You have to have Flash for those buttons to show up and function. So it won’t show if you’re on a phone/device. Maybe some PC browsers don’t show it as well, possibly try another browser (???)
I'm on PC and use Internet Explorer 11 for playing on WGT.
So from your good suggestion, I tried the other browser I have (Microsoft Edge) and the remove friend button was there!
Then I closed the Edge browser and looked again in IE 11.... and what do you know... the remove friend button was there.
I suspect when I opened WGT in Edge it automatically updated my flash.
Thanks MarchieB.
