Your Changes Could Not Be Saved

Probably common but can’t find any relevant discussion. I added Plex Music Server to my My Cloud Mirror Gen 2 through the APS tab in the cloud itself. I am having issues ADDing Library. When I get past Select Type, Add Folders, Options, and then when I hit ADD LIBRARY on the Advanced tab, I get a message indicating Your Changes Could Not Be Saved. Plex sees all my files and folders on the cloud. I can create folders and files on the cloud using the same email address/user as i use with Plex. Not sure if it is a permission issue or what. Am really looking forward to using Plex but i just don’t seem to be able to create a library. One more thing, I am not creating a Premium Music Library, rather just a basic music library.

I’m getting the same error for saving new movie posters and for adding libraries. I’m starting to seriously regret buying a lifetime membership for Plex. I’ve wiped my Raspberry Pi 3 twice to fix these issues and they always come back within a few days.
