Shareing web link, can't restrict IP with "File access control"

File access control

Hi, I have set up “File access control” to restrict access to files or folders permissions only to specific IP addresses.
However, today I found that when using the file sharing link feature, it does not block any IP addresses.
Is this a bug in the current version?
I have tested this before on version 18 or so, and at that time, the sharing link could not be accessed by IPs that were not specified in the access control settings.
But today I found that this feature is not working.
Is there a solution to this problem?
Thank you.

File access control version:1.15.1
