Yes! All of The Moneytizer ad units are automatically compatible on mobile.
There are 2 possibilities:
The ad unit can be displayed the same way on desktop and mobile because its dimensions are adapted to all screen sizes. Example: top medium rectangle (300X250 px)
Initially, the ad unit has not been thought out for mobile and it is automatically replaced with a more suitable ad unit. Example: the megabanner (728x90px) is replaced by a mobile banner (320x100px)
