USB Restriction Policy in macOS 14 Sonoma not working

Hello,

I wanted to see if anyone else is having issues with Restricting USB's in macOS Sonoma. I am currently on Version 10.5.1 for Sophos and on macOS Sonoma 14.1.1

Currently, I have the Peripheral Control set to Read Only for Secure removable storage and Removable storage. When I plug in a USB into my computer, I do get the pop-up that USB SanDisk 3.2Gen1 has been restricted to read-only by your administrator, however, I am still able to read, write, delete and transfer files to and from the USB. It worked in the past with macOS Ventura, however it is not working now.

I am wondering if upgrading to macOS Sonoma is the reason why it's not working. I wanted to know if anyone else is experiencing the same issue as me.

Thank you!
