Performed Rovi Update>Xfinity On Demand App Gone from Roamio but Still on Mini

Hello,

I have a Roamio Pro connected to one Mini on Comcast/Xfinity. Prior to receiving the Rovi update, both worked perfectly. I had access to all my channels, including my subscribed premium movie channels and Xfinity On Demand :)

Then I received the Rovi update this past Friday (8/26). Everything's finally back to normal except for one annoying problem :(

Xfinity On Demand is completely gone from my Roamio Pro. It's not listed:

• in the "My Video Providers" menu (Settings>Channels>My Video Providers),
• in Tivo Central (Find TV, Movies, & Videos), or
• as an option to view an episode of a show or a movie if I explore a show.

It's like the Roamio Pro doesn't even know Xfinity On Demand exists.

Then it gets strange. For some reason, I can still access Xfinity On Demand on the Mini connected to the Roamio Pro. It works perfectly, so I can't believe this is Comcast's fault. (And it was working fine on the Roamio Pro the day before I received the Rovi update, so...yeah...)

I already found the Tivo Support website named "XFINITY On Demand: App is not listed or will not launch" and tried everything except for contacting Tivo Support. I was hoping for an easier solution as I hate working with low level, script-based tech support personnel.

Thanks for any assistance!
