Ok, I'm not being clear enough WRT what I did. Sooooo...
. On the Flows tab, I hit the + to start a new flow
. Added three things, button, weather and light bulb
. Added all three to the canvas
. Quick drag and drop to link the Things and updated the settings for weather and light bulb
. Renamed the flow, enabled the flow
. Go back to the Home tab
. Hit the + button to add a button to the Control Shortcuts section
. This pulls up the list of Things but I dont see my new flow as an option to add to the control shortcuts section
So, what have I missed? Sorry for the stupid, newbie question.
