Access media files on Oculus Go with Unity3d Asset

An Oculus Go will likely be required in order to test the issue I have purchased a Unity Asset which creates virtual tours for use on various platforms. Within the asset is a field that can be used to specify a local path to media stored locally on the device. I have been unable to get this path to work on the Oculus Go. 1. It's possible its a permission issue 2. It may be an issue with the asset - if so then I need someone to confirm that for me and modify the asset to work. 3. Something I've just not considered (I have limited Unity Experience) 4. Its possible that i'm just not formatting the path correctly, so far I've tried: /storage/emulated/0/Movies/[login to view URL] /storage/emulated/0/[login to view URL] //storage/emulated/0/Movies/[login to view URL] ///storage/emulated/0/Movies/[login to view URL] file:///storage/emulated/0/Movies/[login to view URL] file://storage/emulated/0/Movies/[login to view URL] file:/storage/emulated/0/Movies/[login to view URL] /mnt/sdcard/Movies/[login to view URL] file:///sdcard/Movies/[login to view URL] /sdcard/Movies/[login to view URL]
