Doesn't work in background – FlashAir Review

I moved from the Eye-Fi to the FlashAir and I'm liking it so far except for one main issue, the app doesn't work when in the background. If you're downloading images and leave the app to do something else, the app stops transferring photos. Super annoying and means you can't use your phone at all while downloading photos.
