If I use the curl example from the dropbox api spec replacing "mute": false by "mute": true
curl -X POST https://content.dropboxapi.com/2/files/upload
--header "Authorization: Bearer "
--header "Dropbox-API-Arg: {"path": "/Homework/math/Matrices.txt","mode": "add","autorename": true,"mute": true}"
--header "Content-Type: application/octet-stream"
--data-binary @local_file.txt
the file is uploaded correctly but , I still receive a file update notice.
