I think it's a limitation with the way the N9 works, but I noticed that when ProfileMatic switches between 2g to dual and from dual to 2g, my N9 completely loses its cell connection briefly. It's not a big deal, but I figured it's worth asking about. When I do this manually, switching from 2g to dual doesn't drop the connection whereas dual to 2g does. ProfileMatic drops when doing both.
