In Experience Space under Where used, the tab "In use by", shows all items: current and old versions. The extra information -as present in classic- on current/old versions is missing.
This is confusing, for example when trying to find out what pages need to be republished using shared components.
All info could be useful, but on first glance showing only the current usage will cover the most relevant tasks. Maybe with an option to see old versions in an extra tab?
