IMPORTANT! Please read.
The add-on uses the storage place as the "single source of truth", this is great, but you need to understand that it has some special behaviors. Like:
If you share the same file into 2 different Confluence pages, when it gets edited in one page, it will reflect that changes in the other page.
If someone deletes the file shared/embed into a Page from the original storage (OneDrive, Google Drive, Dropbox, FPT Server, etc) it will no longer be available in Confluence.
If someone edits the file in the cloud storage or FTP server via a desktop app, those changes will also reflect on Confluence.
This behavior is great to avoid duplicates and multiple untracked versions across platforms. With this add-on you can have 1 file that is the same everywhere. But you need to remember that it's the same single file everywhere. Handle it with care. :)
