why does it say wifi connected but apps aren't working

[Tilly_yo30]

It says my wifi is connected but if i go onto facebook messenger or something, it says 'waiting for network'
this is happening with all my social network apps and has been happening all this week

If your on a home Wi-Fi router try resetting it or just unplug the router and plug it back in.
Takes a minute or two to provision your device which might fix the problem you're having.
