Can't access converted videos anywhere else – iConv: Video & Audio Converter Review

The conversion of videos works well. My problem is I can't access these videos anywhere else. Tried using the photo sharing/cloud option but won't post the videos to my cloud. Tried posting to Dropbox, but would only play the audio. Tried uploading to Instagram...won't do anything. Tried emailing/messaging them, won't go through. These are very short videos (10 sec) thus it's not a file size issue. This app is useless to me.
