Cabnnot connect to MyBook Live 2TB from my phone

I recently got a new Galaxy S8 and had to do a clean install of all apps. I can no longer access my two MyBook Live NAS drives. What is the cortrect app to use for this? (The one that installed only has My Cloud, My Passport Wireless, and My Cloud Home as options).

My Cloud Mobile app ?

The My Cloud mobile app for iOS and Android provides remote access to your My Cloud, My Book Live and Duo devices. The mobile app can also be used for local LAN access to My Passport Wireless and My Passport Wireless Pro.
