I've noticed that a new Interaction Studio app has magically appeared in our Marketing Cloud account today.
There's no documentation on this (at least I can't find any) and there aren't any release notes either. I note that existing Interactions (created in Journey Builder) don't appear in this app. I'd be grateful if someone could enlighten me exactly what this new app is for.
Does this replace Journey Builder? It appears to. That is, you can build and run an Interaction directly from Interaction Studio without the need for Journey Builder. However, I note that Interactions that I create in this app are available in Journey Builder. So, perhaps this isn't the end of Journey Builder. At least, for now.
