Are you trying to upload to your mobile device?
Connect to the phone by pressing the media gallery in the app (under the picture of the phone). Select your media file and the the share icon. You need to do this one by one as group transfer hasn't been implemented yet. You will get the option to save to app.
The Auto transfer/pull down method ("looks like you have new media") only happens for a short limited time after you have recorded the media.
