When you switch Social Sets, you'll see different connected accounts, separate content (drafts and scheduled posts), set-specific analytics, and different inbox messages - all specific to the Social Set you're now working with.
How to switch Social Sets
Go to your Dashboard then click the Social Set menu located in the top left of the page. Click on the Social Set you want to switch into.
The page will refresh and load the selected Social Set's dashboard.
If you are on a team, your team's Social Set will show in the list underneath your owned Social Sets.
