I've had a hard time finding any recent information in regards to the remote control lag on a slingbox 500 when controlling if remotely, via the web app or a mobile app. The lag is specifically related to navigating the connected device. In this case, the connected device is a roku. It takes 10-20 seconds for each remote button press to reflect the update on the mobile app or web app. I can see the update instantly when viewing the TV the slingbox is connected to. Any information would be appreciated.
