I've had V5 installed since available and with I-phone and I-pad, I've seen no improvement in the app staying connected. Nearly 100% of the time I need to reconnect when I switch to Conductor.
This nonsense is why I sold my Aurender after a couple of months. I can't believe something so basic is still a problem, especially at this price level. Great sound or not, I cannot abide shoddy software.
