Issues with latest update

After updating Samsung Multi Room app, I cannot access my music collection on my go flex external hard drive. The external hard drive is no longer listed as an option in the music source list. Also, others have complained about not being able to sign in to Pandora and I have been having that issue for a long while now. It is a great app if they could just fix everything and leave be! Getting tired of unpredictability.
