Turn on Bixby Routines in the quick panel to use this widget

Okay cool. How do I do that? Where is Bixby Routines? Normally it has a checkmark but it's not there? When I want to sleep I want to use the sleep mode, or when I want to study I want to use the study mode, so how can I use the mode if samsung has no way to enable Bixby Routines? 

Fixed:

Had to force stop the Mode and Routines app through the settings

Yeah that's where mine is too. I figured out the solution by disabling bixby and force stopping the modes and Routines app

Tap the pencil near the top right. Your quick settings toggles should say "edit". Tap that and you will get the quick setting button edit screen. On the bottom you'll see available buttons, the modes and routines button should be there. Add to the rest, and you should be set.

Yeah it was not there. It was removed in one ui7
