One of the apps (and its data) doesn't restore from iCloud. How to fix? I'm restoring iPad from iCloud (context) after factory reset, but the app I need to restore from iCloud doesn't show up as scheduled for install: App Store > Purchases shows an icon to download the app from the cloud (which will not restore its data, as I've seen before the reset).

How can I restore the app I need and its data from the iCloud?

I know the app is there backed up as it's shown in the list of iCloud-backuped apps (iCloud > Storage &amp; Backup > Manage Storage > (my device) > Backup options) now after reset-and-restore--and also was there before I initiated factory reset.
My specific situation was that initially I tried a backup version that was too late to contain the app required. Once I switched to an earlier backup, the app was there and successfully restored with all its data.
