This is likely to be because the person who has been added is currently under the age of 18, and Members’ records are not visible until they turn 18.
We are currently investigating a long term solution to notify the Appointment Secretary again when they turn 18. For now, you will need to keep a local record of this Member to action at a future date. When they turn 18, if you log into Compass and search for them you will be able to see their record and start the Appointment Process for the role which was previously added.
