Content Server Mobile Can't edit anything from my smartphone, only see content

Hello experts,

I I have been able to carry out the implementation of the AppWorks Gateway to allow access from cell phones.
The connection works well from cell phones, however, users cannot modify anything or add new items, for example, when they want to add a new folder, an error message appears that says: "The request has been rejected."
And this same user does have all the permissions in the CS

Any suggest is welcome, regards.
