If a staff member can only see their own appointments or cannot access reports, you need to review and enable the required permissions from the Admin account.
In order to share the access,
1. Go to Manage Staff > three dots > Edit > Permission.
2. Enable the “Show Data With All Staff Members” permission to allow staff members to view data and appointments associated with all staff members, rather than only their own.
3. Also, enable the required report permissions to allow the staff member to access and view the relevant reports.
Note: Make sure to save the changes after updating the permissions, then ask the staff member to log out and log in again.
