Hi.. everybody.. did you experience: there are notification from facebook like "friend suggestion" then when open up the notification there is nothing in there... weird... windows 8.1 lumia 535 .. any suggestion how to fix it?
This sounds more like an issue with the Facebook app and not necessarily with the device itself.
Uninstall the app then reinstall. Go to the app setting and customize what features you need, notifications and alerts. Then make sure you sync the ap through the phone settings. If none of this helps then post back on here and we'll see if we can find a work around.
If you get it fixed, don't forget to update us all as to what you did and how, I'm sure others on the forum will be interested to know how you go on.
