Signing into TBS/USA app on iPhone with Cox

I have an iPhone 7 and am trying to access both TBS & USA using my Cox account.  I have been able to do this fine with other stations like TNT & Oxygen, but when I login to the TBS app it says "You are not authorized to view this content.  Please contact your payTV provider for further assistance".  For USA it says, "Uh-oh.  You need to add this channel".  I have both channels on Contour and I watch them on my television all the time. 

I've tried signing out and back in.  I've tried rebooting my phone.  I've tried to uninstall and reinstall the TBS & USA apps.  None of these things work.  Can anyone please help?
