Hello. I wonder if anyone can help me. I have a Nokia Lumia 635, which to this point has been spot on but a couple of hours my toast (and sometimes my push) notifications are have stopped working. I have tried soft reset, hard reset and plain simply shouting angry words at it but to no prevail. Have any of you guys had this problem. I'm also on O2UK. With no data left in my allowance but I am hooked up to WiFi.
