For a while now I have been getting an increased number of notifications on my Me Life Tile on my Nokia 920 that does not clear after checking them. Before I would go to the notifications window, checked all the highlighted new notifications in red, gestured upwards and they were cleared, now this only changes the colour of the notifications but it continues to show on the life tile and the number keeps growing, I now show about 32 new notifications but there isn't any new ones! any ideas as to what I can do clear them?
