Hello IT Support-HO,
Thank you for posting in Microsoft Community forum.
Because folder redirection is user configuration, please check if you can see the group policy result.
For checking User Configurations within gpresult, we can follow steps below.
Logon the machine using normal domain user account (that applies this gpo).
Create a folder named F1 in C drive.
Open CMD (do not run as Administrator).
Type gpresult /h C:\F1\gpo.html and click Enter.
Open gpo.html and check if there are these gpo settings under "User Details".
If not, please make the domain user account is in one OU and link the GPO with folder redirection to this OU.
For more information, please refer to link below.

I hope the information above is helpful.
If you have any question or concern, please feel free to let us know.
Best Regards,
Daisy Zhou
