There is no "Publish" button, only a "Post" button.  When you press "Post" it does not redirect you anyplace, instead,  the Timeline below updates and the expanded "Post" dialog remains expanded. All our users want the "Post" dialog do go back to its unexpanded state.

Its current behavior is detested by our users as in the mobile app the Post dialog takes up all the viewable area.   If you're saying that it's not possible to have a different behavior then UNA is a very flawed ecosystem that can not meet user expectation.
