Facebook is removing App Profile Pages - This affects a lot of Devs

Today, we are announcing that we will remove all App Profile Pages on February 1st, 2012. Though similar in appearance, the automatically generated App Profile Pages differ in features from traditional Facebook Pages, and over time the inconsistencies between the two, such as different Insights, APIs, and distribution channels, have become more apparent.

If you have an App that you add to Pages as a Tab by sending Page Owners to the App's own Profile Page, then you need to change how you do things.

The easiest way is the URL example they give. You can set that up and just tell people to go there and click on the Page which needs the Tab.

Probably a bigger documentation issue for companies like ours rather than being a technical issue.
