What happened?
Updated appdaemon today and it doesn't start anymore. I am getting error Unknown field: appdaemon.plugins.HASS.hass.app_init_delay. I do not set this field in my AD yaml config.
I updated both appdaemon, which was only a version bump, and also updated HASS to 2026.2 at the same time.
