the on demand tv shows catagory has changed to a one line list everything right below each other. None of the catagories can be selected. for examble by network , or Shows A-C HD. What is going on ? The Movies catagory works properly and you can watch the movies but no tv shows. Looks like this.
Xfinity Top 20
Shows A-C HD
etc , etc
I saw this late last night/early this morning also; by breakfast things were back to normal. Not the first time I've encountered the issue; happens while maintenance is performed?
I was able to "Search TV & On Demand" from the Main Menu to get to the program I wanted while the On Demand menu was broken.
Hope all is okay for you now, as well.
