xfinity App

I use the Xfinity App on my iPad.  Recently, when I clicked on the icon, I received a message telling me that I needed to up date the App.  When I attempted to update the Xfinity App, I was instructed that I needed a higher IOS version.  I have the highest version allotted for my iPad.  That is, Apple says I am up to date.  

I now have no Xfinity App.  This is non-sense.  

I am on a fixed income and cannot not just go out and purchase a newer iPad.  

Does anyone have a recommendation of how to make the existing app work without telling me that I cannot use Xfinity App until I update which I cannot do?

Disappointed with Comcast again.

Sincerely,
