"Notifications" item in mobile app no longer works

Clicking on the "Notifications" entry in the iOS mobile app results in a modal "Loading Notifications…" dialog that cannot be dismissed and stays there forever. The only way to regain functinality in the app is to force-quit it and start over.

When clicking on "Notifications" on the app, the hub logs the following message:

[warn] Received cloud request for App 29 that does not exist, path: /menu/notifications/2 from xx.xx.xx.xx

This is with the latest hub FW (2.3.3.125) on a C7 - I'm not sure at what point this stopped working, maybe with 2.3.3?

I just tried it on my app and it worked. Wonder what might be causing this error for you?
