Yesterday I went to the Automations page, and got the blank welcome page (see attached).
I have not messed with a single .yaml file in over a month. Nor have I even created an automation, I believe.
Any idea what could have done this?
I tried rolling back three backups, same issue. Scenes are still there.

The line
automation: !include automations.yaml
might be missing in your configuration.yaml

That’s in there!

does automations.yaml have any content?

And check your configuration in 
-> YAML

Perhaps you moved your automations.yaml to a folder? If you do that, and create a new automation, the new automation created from the UI will regenerate the automation.yaml in your config folder, making it look like you have lost your other automations.
I recently did exactly this 🙂
