I have reported bug #435 and the log showed it was fixed in 0.8.2.
We updated to 0.8.3 today, and find similar issue as before.
I exit my iOS application by pressing Home button, and reentry the app by click the icon. My app always start from first page. If I remove the play sound and play music functions, my app can start from the page I exited when I pressed the home.
Maybe the problem still there?
