Android not updating from 6.0 to 6.0.1 for Moto G 3rd gen
According to the discussion on the official Moto forum, it seems that the updates are inconsistent.

USA devices are all on 6.0.
Indian devices are all on 6.0.1.
European devices are inconsistently on 6.0 and 6.0.1, even though the devices may be from the same country, purchased SIM free from retail, and on the same network.
