streaming apps on contour

I also have been unable to stream AppleTV within the Contour apps for almost six days now.  I get the "something is wrong/no internet connection" message. I have cleared the locally stored data and refreshed the system.  I called tech support this morning and their solution is to replace ALL my receivers.  This is unacceptable.  They also said they would charge me $75.00 for a service call if they came out to swap out the boxes.  And from reading about this issue on this forum - I am not sure that will fix the problem even so.  Obviously, Cox and Apple need to work this out.  If it is a software update with Apple, Cox hasn't quality tested their equipment and software.  I understand that 3rd party apps are not Cox's responsibility but if their is a firmware fix  - Cox needs to step up!
