We use the free jira version with team-managed projects. In the last weeks, we also tested a few apps from the marketplace.
Now we are running into a problem: We installed an app (in the example below "Workflow Magic Box"), which is also shown in Settings -> Apps:

However, the app is not shown in the left side bar although the marketplace clearly shows that the app is installed.

Is there any chance to add the app the side bar?
(Even more) interestingly: The apps were all installed by myself. My colleagues, though, only see one of the installed apps (Deep Clone) and do not see "Issue Template Agent".
