I created an Automation with 'Any time AcyMailing is triggered'.
With a condition:

An Action:

And the Action Target:

And then activated the automation on the Summary tab. The number of subscribers on the Expired Members list did not change from its previous value to '5' users.
Configuration/queue/advanced reports:

So AcyMailing was triggered but the list did not update.

Why didn't the list update to show 5 users?
