Lost 3 or 4 times 15 min on the last 2 days just because sketches are gone anytime the iPad (13.3) screen goes off...
Meeting notes, sketches, you speak for 2 min, come back and... gone.
It's been ages since all devices are on batteries and OS's are protecting against drains. I can't imagine all developers saying "OS are optimising battery life thus, yeah you loose your work"
Incredible!!
