Files Column no longer displaying SharePoint shared Libraries

Hello:

I have a board with a “Files” type column which worked great as I used the “From OneDrive” option to be able to link files from OneDrive and more importantly SharePoint groups. Yesterday morning, I used the column and linked a file from a SharePoint “Shared Library.” Then someone on my team complained it was not working for them, so I signed into Office 365 from Monday again and WHAM - it no longer shows Shared Libraries for me. Any ideas where the issue may be? See attached, Shared Libraries used to show between Recent and Switch Account,

Thanks!
