I spent days checking out everything to no avail. Both devices using the same iCloud account, entitlements and provisioning profile in order, code correct, waiting patiently for a notification: nada. In total frustration I powered off both devices and restarted them.
Voilà!
Now I'm getting notifications consistently, and reasonably quickly.
Thank you all for all the helpful tips.

But for the life of me, I cannot get any changes to KV storage to propagate to iCloud, or get a notification back if a KV item changed.

After that, I never receive any notifications again on that device when the the same app running on another device changes the NSUbiquitousKeyValueStore (or the same app running on the same device for that matter).
