That said I noticed when checking it out that the surfacing of activities from related records to parent accounts does not seem to work. Using the web client when you look at a parent account the activities, cases and opportunities are rolled up from sub accounts. This gives the user a complete picture of all interactions in a company hierarchy. This does not see to happen in the interactive service hub. If you look at the screen shots below you can see the difference when you view an account in the new ui and the web client.
There is now a new form type called “Interactive Experience” for the Interactive Service Hub and when you customize this type of form you will see that the dreaded Social Pane/Notes component is gone and has been replaced with a new component called Interaction Wall. I could not find a way to configure the Interaction wall.
The ability to view the hierarchy for an account also seems to be missing. At the moment I am reluctant to use the interactive service hub until I am confident it is not missing currently available functionality.
