How can I unblock app notifications?
You can do that here: vk.com/settings → �View blocked apps�.
If you have restricted a specific friend from sending you app notifications and want to undo that, you need to wait until you receive a notification from an application (for this, you could ask another friend to send you a notification).
Then in the "Games" menu, there will be a new "Notifications" tab (vk.com/apps?act=notifications), and to the right, you will find a "Blacklist" button. It�s there that you need to look for the name of the friend whom you want to receive app notifications from again.
Your search for returned no results.
Try using other keywords, e.g.: "delete profile", "create chat".
Check your request for misprints.
