I have found that I have this problem about every 1 out of 3 restores. It's not that important to me considering all of the devices that already beep when I get an email But I guess restore constantly until it works?
Hmm restoring seems like a pain :/ Maybe for beta 3 I will make sure to do this if it's still not fixed! @tinyman, guess your lucky I am not. Been happening for a while D:
