Dropbox and iCloud sync not working as expected

althought my internet connection is 10Mb/s upload syncs feature of this app seems to not work. Both dropbox and icloud sync are not working. Please rewrite the sync code, becouse now is NOT working.
if i use dropbox sync i get a notice fromdropbox app every 2 seconds that a file was added in my cloud folder. It’s an annoing bug.
