Users are able to set their email notification in the folder options. However, if you have "viewer" access, you are not able to select these notifications for uploads. You must have "editor" access to do so.

We have groups with "Viewer" access as they shouldn't need to edit files in the said directory, however they should be notified when a new file has been uploaded.

The only solution box support provided was to turn on the upload notification in the user settings for all of their files. This would be counterproductive as the clutter of notifications for all uploads would remove the importance of notifications on the few folders that need to be tracked.

If a user has "viewer" access to a folder, they should be able to enable notifications regarding uploaded files to that folder.
