Smart View/ screen cast not working on S9 plus after pie update

[SuperGravy707]

Before the pie update, I was able to cast videos directly to my LG TV with smart cast or view or whatever it was called. After the update, I can't even get the screen mirroring to work

I found it! Use the top pulldown menu, as before. SmartThings shows up with a "cyclone-looking play button" icon to cast to my TV.
