Just had my 2 defective HR20's replaced yesterday with HR24-100's. TV Apps isn't working on either receiver. Apps are working fine on my H21. The first time I hit the right arrow button, it says that TV Apps are loading, then nothing happens. When I hit it a 2nd time, sometimes the app menu bar appears and other times I get "Service Unavailable (7)". When the menu bar does appear, I am able to select the App Store. That part loads fine. I can even browse the available apps. But when I select an app to add, it just sits there for a while and then the message "Sorry, we are experiencing some technical difficulties. Please try again later." I can immediately go to my H21 receiver and apps are working just fine. This is only happening on both of my HR24's. Never had this issue on either of my HR20's before. Anyone else having this problem?
