Xfinity Stream app on my Fire TV always had the Closed Captioning on eventhough I have repeatedly set it to off.

Only in the Xfinity Stream app on our Fire TV  does Closed Captioning (CC) always default to ON, every single time a new channel/program is opened.  I love that you're into Accessibility (thanks), but we want the ability to set the CC DEFAULT to OFF.  How?  I checked in the Xfinity Portal ... Settings > Accessibility > Closed Captioning is OFF.  I checked in the Fire TV device's Settings > Accessibility, also OFF there.  But again, every time we open a new channel/program within Xfinity Stream app on Fire TV, CC starts as ON (default).  We know how to turn if OFF by navigating to the icon, but we don't want to have to do that every <darn> time. There's gotta be a way to set the Xfinity on FireTV CC default to OFF but we cannot find it.    Please don't reply with a link to the existing Accessibility CC Help page.  That doesn't address the issue.  We're talking about controlling the *default* behavior in this specific app+device scenario, as outlined above.  Please note that this only occurs with the Xfinity stream ,the other steaming services, Amazon Prime, MAX all have no closed captioning on.
