Money wasted: iCloud and Dropbox don’t sync! EDITOR’S CHOICE UNRELIABLE

I already had the iPhone and iPad version, and I bought the Mac version to be able to move from iPad to Mac.
Astonishingly, Dropbox and iCloud both do not work.
Just few examples.
1) I save a file on dropbox (or iCloud) on iPad
The file should appear on mac, right?
It doesn’t! Even after 30 mins (maybe forever).
However, astonishingly if you create a directory on Dropbox, the directory is created...
2) No way to move files inside subfolders on Mac
3) On Dropbox the workflow does not work.

My money has been stolen.

The Editor Choice: we cannot rely on it!!
They should cancel the recommendation from the app.
