Facebook has been changing so many things the last few months. I’ve been asked why some weren’t getting notifications on their facebook when things are added to the page. I’ve looked around and was told you need to check off two area. I’ve included the photo.
You will need to go to the page first, then click on “LIKED” then check off on “Get Notifications” AND “Show in News Feed”. Those two will ensure that you’re alerted to when things are added to the page. Hope this helps.
