Emailed guest links no longer work after session edit

The invited guest link that is sent via email to external guests to access the session no longer works after session edit and saving changes.

External invites are removed from the list after making any changes on the session. If you re-invite this person again after the removal, it will generate a new invitee guest link.

Blackboard advise us that the generic guest link isn’t changing, so you could use this to invite guests into the session.
