Background: Clouds gets turned off for certain countries outside of the US. When you turn on the printer for the first time, it asks you to select your country. It's expected that you'd select your own country (why wouldn't you?), but this action hides the Clouds button.
The confirmed fix is simple. To get it back, go to: TOOLS - SETTINGS - LANGUAGE, and then select UNITED STATES. This doesn't change anything important (aside from the visibility of the Clouds button) and still lets you choose the language you need. Feel free to choose English, Spanish, German, French, etc..
