I just updated to android 11 ui3 on s10 plus. Now smart view will not show ez tv on the available list, it shows next doors LG tv though on that list. However it will cast via the ez tv app. This seems to indicate there is a device connection. But smartview has been sloppily coded and needs fixing. I could be wrong, but if it works with non samsung items, but not in the smartview with other non samsung items, but will cast in a non samsung app. samsung can fix it if they want to. Any spin statement to avoid embarrassment at this stage that its going to be a security addon will show it to be false.
