Notifications only received when using mobile data, not wifi

[Squelchy220]

The facebook messenger app for my Samsung Galaxy Fame only receives notifications of messages when connected to a mobile data network, not when connected to wifi. If I swap to solely using mobile data after a conversation, I receive a string of notifications of all the messages I've just been sent in the conversation which is very frustrating.

Have you tried turning mobile data off before going on FB? Some message apps won't work right when you have both mobile data and wifi available. (It's like they get confused, trying to figure out which connection to use, so they just don't use any.)
