Manager Search Result by Hierarchy

Content

Hi,

Anyone can help How to restrict the Manager search result on My Team > Learning > Search by Learner ? We have requirement that Manager should only viewing his/ her subordinate only based on the hierarchy.
Currently we already set the person security profile for Line Manager Access Role using 'View Manager Hierarchy' but still not working. The manager still can see other employees learning record outside his hierarchy.
FYI, we're currently on NUX and this function was working before 20B on Classic UI.
Pls advise

Thanks,
Erika
