Permissions issue with libreoffice docs - unable to edit shared documents

Libreoffice documents are read-only on shared folders.

Here’s my problem: I have shared a directory that holds Libreoffice documents that I authored. The share person can open the documents but not edit them. (they are opened read-only). I’ve adjusted the permissions on the author side of the share to 666 or 777 with no positive outcome.

This same scenario played out in Dropbox works; I.e., the share person can open, edit and save the document.

I’m running Nextcloud 10, desktop clients are owncloud 2.2.4 running on Ubuntu.

thanks for all the hard work in giving us control of our data!
