The first element available in the main screen is the site selection.
This new site selector benefits from useful features such as an integrated search engine to facilitate access when searching for something specific. Multi-site selection makes global, group analysis possible directly within User Insights. Please note that multi level 1 site selection is limited to 50 sites.
Level 2 websites can also be selected from the drop down via the icon at the end of each line:
Only one level 2 site can be selected at a time.
Coming soon: Multi-level 2 site selection.
