No Video While Playing Through xfinity.com/stream

@XfinityKimberlyB​ Multiple times, in both browsers.  Quit and reopened browsers multiple times.  Rebooted macOS multiple times.  Disconnected all external monitors.  Problem still persists.  Nothing jumped out at my viewing Crash Reports, not viewing behavior with Activity Monitor.  I can't remember exactly when this started happening the end of last week sometime, but I do recall updating from macOS 13.0 to 13.0.1.  That would be where I would start looking first.

Thank you for sharing that information with us. Have you tried logging in to Xfinity Stream on a different device? 

@XfinityCrystal​ Yes, without issue on an MacBook Air 6,1 (Mid 2013) 8 GB RAM, macOS 10.15.7m, Safari 15.6.1.

In Apple's release notes for 13.0.1, updates to libxml2 were made, the only 2 mods documented.  Not sure if xfinity.com/stream interfaces with that library or not, but perhaps the mods to libxml2 broke xfinity.com/stream?

@XfinityCrystal​ , Attached is the Chrome window on my screen.

@XfinityCrystal​ Attached is a screenshot of the Safari web inspector errors pane.
