I see that the IQ2 is essentially a clone of the main IQ panel. That said, when I touch the weather icon on the IQ2 panel, it does not retrieve the 4-day forecast like it does on the main IQ panel. It seems all other features function just fine, but not the weather icon.
My understanding is that the IQ2 panel at this time does not deliver four day forecasts, only the current day. There has also been yet another patch released just a few days ago!!
