AT&T Galaxy S8 Where did Smart Network Switch go?

[mcefalu]

Since the Oreo upgrade to my S8+, smart network switch has disappeared. Currently, on the notification bar the wifi icon and 4Glte and the horizontal bars appear. Prior to the upgrade, either the wifi icon or the 4G icon (with horizontal bars) would appear depending on which was being use at the time. Has the smart network switch been removed? Name changed? Anyone have any clues?

It's just "switch to mobile data" now, you have to hit the slider now if the update deactivated it. Settings-- connection-wifi. Tap the 3 dots, select advanced and it should be the first option
