Pause and rewind

Hello @user_cf10b1, thank you for being a part of the Comcast family and for taking the time to reach out to us. I am sorry to hear that you are having concerns with your X1 Cable box with the pause and rewind feature. Have you attempted any troubleshooting steps for a resolution? Just a friendly reminder, if you are ever experiencing issues with your equipment/services, you can troubleshoot your devices by downloading the XFINITY My Account app. You can also manage your account and appointments with the XFINITY My Account app or web link https://comca.st/3FYy8oW. I really love this app, I use it all the time when I have concerns with my services. The other day my services were acting up, once I ran a few troubleshooting steps I got my Cable working properly before it was a bit sluggish. I highly recommend using this app whenever needed. I love that Comcast does an amazing job of making it easy for you to manage your account and services online. 

Installing an app on your phone does not sound like a valid fix for your problem but rather more self-service.
