Signals Notebook: Permissions added to a notebook are not being cascaded to the contained experiments

Problem: When adding a new user with full control permissions to a notebook, the permissions are not cascaded to the experiments in the notebook. Adding the previous user will not fix the issue.

Cause: This happens because notebook-level permissions can not longer be cascaded to experiments within the notebook if all users with access are removed at some point. For example when a full control administrator is transferring Notebook A from User A to User B and User A is removed before adding User B leaving the notebook temporarily without user access ("Not shared with anyone").

Solution: This is a known limitation of the application. Always add the new user before removing the old one from the notebook to maintain the ability to cascade permissions.
