I added a if this then that (bixby routine). I clicked add an action and in the section at the very bottom it had an option to add a dashboard widget. Where is this dashboard? I've tried everything to find it (swiped down, right, searched). What's the point of adding a dashboard widget if the dashboard itself doesn't exist?
When you go to Settings>advanced features>Bixby routines you should see the dashboard. Also now that you have enabled it, you can now go to the Bixby routine app and your dashboard is there.
If you pull down your quick setting, there is a notification that is running for bixby routine that is running...press the blue button on the right of that notification. Also, on the home screen, if you have face widgets on, you can swip until it has routines...press that and the dashboard will show on your lock screen (if you have face widgets/routines on your lockscreen)
