I have a 32GB drive formatted securely with my Nexus Player and being used for all app and Game data. However when i tried to add files like Movies, Pictures, or EMU ROMs, ES File Explorer is not able to read the drive. Will I need to use another USB drive that is not formatted for this purpose or does Android 6.0 on Android TV no longer allow for "user write" access to the USB drives?
I use ES file Explorer to send movies to it. Definitely not the best solution though. Another method would be to use drivesync to sync files from Google Drive to the player. For that to work though, you'd need to sideload drivesync, and have a mouse to set it all up.
