Volume and Mute not working

@XfinityChelseaB I’m lame on these forums, not quite sure how to follow along. What happens next?

@XfinityChelseaB I haven’t heard anything from anyone. 

The same thing is happening to me.  My mute button only works for the duration of the button press.  If I hold the button, the mute function works, but "Accessibility Shortcuts" pops up.  None of the directional buttons in it respond, so I just have to wait until it times out.

This is certainly not the experience that we want you to have with your remote while trying to enjoy your shows @user_3604d2.

You can use this link https://www.xfinity.com/support/remotes to try and troubleshoot the issue. It also shows you the model of your remote which can further help us with this. We also have the Remote application that can come in handy when your batteries run out, there is issues with the remote or when it goes missing.
