Error tvapp-00209 after changing channel lineup

Recently had to make changes due to promotional ricing ended on my account.  After the change, the xFinity Stram app on my ipad no longer functions properly.  the app opens, but when I click on ANY channel I get error tvapp-00209.  Here are the steps I have done so far:

1. restarted the ipad

2. restarted the gateway

3. restarted x1 cable box

4. uninstalled and reinstalled the xfinity stream app on the ipad.  

None of those steps has resolved the issue.  

How do I get the app to work as it did before the changes to my plans?

Thanks!
