Updated Hass.io 0.80.1

Unfortunately, the update has not fixed the Automation but also appears to have broken a few of the other tabs including all the dev tabs.

what automation are you referring to?
Also what tabs are broken?
Can you be a little bit more explicit?
All works for me…

To get to automation >>> Configuration >>> Automation >>> “+” = blank

tabs that are broken are under development tools >>> and all other than “Services” are broken.

Sounds like something related to your setup.
Try and rename your configuration.yaml and create a new blank/basic one and see if it’s still broken.
I don’t write my automations in the UI so I’ve never made the migration to add the automations ids allowing me UI edition and as such I can’t use Configuration >>> Automation >>> “+” but all other tabs show correctly for me:

This appears to have self corrected overnight. I have literally done nothing.
