3. Launch the CCX course unit with the LTI consumer XBlock.
4. Go to http://localhost:18000/admin/lti_consumer/lticonfiguration/.

6. Update any value on the main LTI configuration.
7. Go to the children CCX LTI configuration.
8. The values from the main LTI configuration should be reflected.
9. Delete both LTI configurations.
