ST made the recent change with their latest app release:
- Scenes are now called “Manually Run Routines”
- Routine are now called “Automatic Routines”
There is a current thread on issues with Routines: Automatic routines not working as of yesterday (17 Sept 2023)
For myself, I had a couple that stopped functioning properly in mid September… the actions for all devices in the Routine would not occur. I found, deleting the Routine and recreating it solved that issue for me. Editing and saving the Routine did not work… only deleting the Routine and recreating.
But read through the thread I linked to above… there may be helpful information for you.
