New Firmware Update Problem - Full Permission to Public Folder is lost after the update

After the firmware update v04.04.00.307, I lost full access (write access) to the Public Folder. Rebooted several times, the problem still exists. Can anyone please let me know how to rsolve it? It works perfectly fine before the update. 

Thanks in advance!

Call support and ask for the patch that fixes permissions on sub folders in the Public share.

Worked for me.

Apparently it has something to do with using Desktop App or something and then using Samba without logging in as a device user.  Anyway… patch solved it for me.
