Anyone having problem with Mi3 FB like me do?

Sometimes no connection even my other apps like what's apps are working fine,
sometimes can't load anything, the page is just blank;
sometimes whenever it can loads, the interface like old time Facebook that using browser to view.
sometimes can just see the msg, notification but take time to load.

I've asked this few pages back so i'm asking here again.

i use unifi also like that, use my own line also like that.

the "show popup windows" is semi transparent when i tap on it, nothing happened.
