On Xfinity Connect App - select Dialer, prompts to setup Voice2Go. Select Get Started - get splash screen: Voice2Go Unable to process your request. Please try again 
Try activating from Webpage instead. Get to Setting - check all boxes, click Turn on Voice2Go button, just 3 dots continually blinking. Tried multiple times, even left it running for most of the day, still nothing but the blinking dots.
