A fix for what, N2 or N3?
As N3 hasn't been rolled out yet, there can't be a fix for it. And as N2 was only ever a temporary measure, maybe that's why people haven't put that much effort into sorting fixes for it.
The best thing to do when N3 kicks off is put your old boxes away in the attic or somewhere and wait and see what happens. That's all anyone can do.
