Update -
Resolved my issue don’t know if this will help others-
I use Kaspersky Pure, after reading many posts about checking your firewall I finally did. I was sure since it worked before the firmware upgrade it would not be the firewall.
In my firewall network settings, originally my network was set up in Kaspersky as “public” not “trusted”, changed it to “trusted” , rebooted and the magic happened I can now use my MBL with network mapping and see all the shares and folders.
One of the reasons I did not check this before is my music located on the MBL drive was available to itunes on my PC, therefore I did not believe it was a firewall issue.
Good Luck!
