I am unable to add "notifications" to the "Realtime Update Subscriptions" of my app in Facebook. In the "Realtime Updates API" page of the Apps Settings in developers.facebook.com, I have the following settings:
Object: user
Fields: notifications
Callback: http://myserver/callback
Verify token: my_token
if the Fields is set to "feed", it works, but if I attempt to save with Fields set to "notifications", it failed with the following error:
Error Couldn't save 'user': Application cannot subscribe to notifications
Is there anything I need to configure? I have tried adding all "Permissions" under "Permissions" page.
Any input will be highly appreciated! Thanks in advance!
"Note that you can not subscribe to changes on all properties and connections of the User object. Connections to which you can subscribe include: feed, friends, activities, interests, music, books, movies, television, likes, checkins, location, events."
