Multiple issues can be added at once to a team managed project and Clearing a parent issue from the board also clears all of its subtasks regardless of each subtask's status are correct.

The ability to add multiple issues at once is supported in team managed projects through bulk create or import flows and through the simplified issue creation tools that let a team quickly create several issues in one operation. This makes it easier for small teams to populate their backlog without needing shared schemes or complex administration.

The board behavior where clearing a parent also clears its subtasks reflects the simpler, project scoped board rules in team managed projects. The board treats the parent and its subtasks together for visibility on that board so removing or clearing the parent from the view will also remove its subtasks regardless of the individual subtask status.

The issue navigator cannot be enabled for team managed projects is incorrect because issues from team managed projects can be searched and viewed in the global issue navigator and issue search is not blocked for this project type.

Team managed projects support sharing of workflow and field schemes with other projects is incorrect because team managed projects use project specific, non shareable schemes. Workflows and fields in team managed projects are configured inside the project and are not intended to be shared across projects the way company managed schemes are.

You can configure a default issue security level at the project level is incorrect because issue security schemes and project level default security are not provided in team managed projects. Issue security levels are part of shared schemes in company managed projects and are not available in the simplified team managed model.
