I know there has been at least one other discussion on this, but it got wrapped up in the whole "APP' directory should be turned off by default discussion.
I want to report a clearer(?) issue. I recently upgraded to API v2 as required.
I make a write call with
'Dropbox-API-Arg': JSON.stringify({"path": path,
"mode": "overwrite",
"mute": true})
I still get a desktop notification.
I confirmed I have the latest client version.
I am on a MAC.
