Facebook page admins hate how only a fraction of their fanbase will see their posts. In October, Facebook allowed users the ability to get a notification whenever a page makes a post, offering people to stay connected to the pages they care about most.
Now some users are seeing a prompt to receive notifications from a page after they like it. Right after clicking the like button, a box popped up asking if the user wanted to get notifications from the page.
