Small but helpful update to Smart Stack in watchOS 26 - now gone.
Me a few days ago:
New quality of life update - you can click on the date in Smart Stack to enter your calendar. Now you can free up a widget if you had a dedicated “Your Schedule” widget set up.
Yesterday, Developer beta 6 got rid of this feature. Hopefully it’s a bug and we get it back. It adds more utility and is a no-brainer to keep that function.
