Looks OK on my Ipad 2 and an old android phone. If it's still playing up perhaps try clearing the browser cache?
Ok I had the notifications on my iPad but not on my iPhone. Just realised the difference is that I had the style of the site toggled to 'drift child' and not 'default' on my iPhone. Changed it back and I have notifications again. So it's disappeared from drift child for me but fine on default.
Will add pictures in a second!
