When activating a new Journey with a schedule type of 'Run Now' or 'Recurring' the system used to automatically create an automation with the Journey. The automation name was the Journey name with a datestamp appended to the end, and the only step was the activity 'Journey Entry: Audience'
I am now noticing this automation is no longer being created for new Journeys. I used this automation as a fail-safe to manually inject contacts into Journeys past the initial scheduled date. Not the end of the world to do things differently going forward, but I'm just looking for confirmation this is the new expected behaviour.
