Linked In app

Hi All, Recently started using my first apple device, I phone 4S, I was looking forward to using Linked In on it as find the web site fairly triggy to work with. However, when trying to send a message on the Linked In app after selecting recipients using voice over, it does not enter the names into the field? Is anyone using linked in app for sending messages successfully please as it may be me or there may be a work around to this issue. Also, is there a protocol for making the app developer aware of such issues? thanks Colin
