There is no exit button showing. Top left of screen says "notifications" , farther to the right is time - noe "5:53p"- middle of screen has vertical row of 4 blue circles followed by rectangular blue boxes-just below that in white "No New Notifications" - under that" You're all caught up" and farther down
gray box "Notification Settings"
All this is superimposed on top of the movie that isplaying.
I restarted the whole tv thing and now it's all good. Sorry to have bothered everyone. My husband had a stroke and his mind is all messed up but the tv remote is like his security blanket and he just keeps pushing buttons. He used to know how to fix everything but now I have to figure it out. I'm glad you all are here - I'm sure this won't be my last visit. Thank you all for being here.
