Signing out of Sling, or deleting the Sling app will allow you to go to the Home Screen like normal but as soon as you sign back-in to Sling, or relaunch the app, the loop starts again. So, it is only a temporary fix. If you launch Netflix from your remote keypad then go to the Home button, that seems to work too - until you relaunch Sling. I think this issue started after the last Sling update.

I am experiencing the exact same issue with Sling app hijacking my new LG OLED Home Screen.
