The android app at times show a modal dialog box for confirmation and sometimes shows as a non-intrusive green bar at the bottom of the app.

The non-intrusive one seems to be professional and aesthetic in appeal. After a bit of research I found out that when you open Zoho Social app and then chose the media to publish the non-intrusive comes. When you reach to Zoho Social app from Share shortcuts of Gallery then the modal dialog pops up.

Would be good if the modal dialog feature is retired from Zoho Social in favor of the non-intrusive green bar. 

I vote for the green bar.
