We setup an announcement or content and we find the content and signals initially get added and work together without updating the second. We then can change it and again the signals self update. But this seems not to work all the time. We of course duplicate a presentation to create a new presentation and change the content info. We end up having to run them independently which is a real shame and very annoying as it is open to contact manual errors. If is obviously supposed to update automatically and be linked but it just isn't doing so.
