DVR over app is [Edited] as all get out

Why is your DVR service so [Edited: "Language"] on the app but work fine on my TV?   My iphone 14 pro max is connected to my Xfinity Wi-Fi and halfway through a show the video freezes. The audio keeps playing.  if I skip forward its just audio only, but if I rewind back, it’ll start working until it freezes again the same spot. why is it [Edited: "Language"] is the app?  It’s frustrating because of how expensive it is for Xfinity to get this poor level of service.

I come here to report it and selecting the DVR tag causes the page to crash.  Good grief.
