My 77" s90f has been going to screensaver constantly during google cast since the tv updated 2 days ago. Worked flawlessly everytime casting everyday since new until after I got an update completed message on screen 2 days ago. Now it goes to screensaver while streaming and I have keep pressing the remote button to get out of screensaver. Please roll back the latest update!!!
I have the same problem with 55 inch S90f. I have been working diligently with Samsung customer support. I spent over 2 hours last Friday with factory resetting and nothing worked. Even they don't know how to fix it.
