Today, I went to open my Slingbox Android app and noticed that the button to cast to my Roku (the red button that was in the right-hand corner before) had disappeared. I use a Slingbox M2 and had never had big problems connecting to it before this. I checked and it doesn't seem like the app itself updated to remove any features. I tried uninstalling and reinstalling the app to no avail. Anyone have a fix?
