Regarding Synchronization

Hello : i am learning to use mendix to develop mobile application. I have Mendix studio pro 8.2.2 in my desktop. But I am learning  to develop app through mendix studio(through online). I have started developing an app in my online portal. To my astonishment, initially it got reflected in Mendix studio pro 8.2.2 . I realized that the synchronization occurs since both of them operates using same account . I deleted some of the pages of the app and created new pages, in Mendix studio(online) but now it is not getting reflected  in Mendix studio Pro(desktop). Can anyone help me with this?
