I'm trying to use the Suppression List (August 2021 feature) in AJO (we have profiles with duplicate email addresses which we need to exclude).

I've tried adding one by one and with the CSV upload (status says it was complete), but nothing appears on the list screen. Do they take time to appear or is it just not working?

It appears that it can take some time for updates to the Suppression List to appear. So it does work and just takes some time.
