Hi!
I noticed some changes in ACS service creation and according to the latest release notes, services are now attached to an event instead of a transactional template. Despite this change, is it still possible to not use subscription confirmation messages?
With the service I'm currently working on, I don't want to use an unsubscription confirmation message. However, when I delete the unsubscription confirmation, ACS says that the field is required and won't let me confirm and save the service (see my screenshot below).

Is this some kind of a glitch or meant to be? How can I use services without using confirmation messages?
Br,
