express not syncing

Hi, I started usin express couple of weeks ago as it seemed like the perfect tool for my needs. I need to make posts fast on the go, but they are easy to prepare before hand. However. I stumbled upon a huge problem right away. The web app that i'm using on pc does not sync anything to my phone app. Absolutely nothing has been synced so far. I'm running the latest software on my iphone as well as on the phone app. I have tried logging in and out, as well as deleting the app. Nothing works. This app is of no use without the sync.
