I loaded up both apps at the same time, only starting to navigate one the BSA was loaded fully.
The city wide app is just that, you've got the map and book marks, no interactions with the data at at.. so it's really the basic view.
So, the Digital Twin, I realise you've used the same map, however, with the graph and bookmark widgets have you created any particular data views or sorting? Do you have any actions set?
I think you've got actions on the map and graph (framework), and it is this that's giving the difference in what you're seeing.
