[iPad] Waiting issue

 

Hi,
 
The problem has been solved (by time), but I wondered if any of you have come across this and what might be the reason for it.
 
Two days ago, I purchased a new app and at the same time set my iPad to download 11 updates.  All of them got the "waiting" status.  Then nothing happened, until my iPad (which I wasn't using otherwise) turned itself off.  So I turned it back on and the "waiting" status on all of them continued.  This went on for several hours (I didn't sit there all that time, turning it on, but I checked periodically).  I left the house at one point, and then when I came back they'd all be updated.
 
What would cause that kind of delay?
 
Thanks, Carolyn
