When I connect to my sling-box on my iPhone app, the connection speed is ALWAYS (SD) quality. I have the settings set to HD quality. I am connecting on an LTE network with 30mb/s speed. I have also tried to connect with connected to a router. The ONLY time the app will connect at HD quality is when I am on my home network! This did not occur in the past. This just started occurring within the past couple months. Any ideas???
