[Plugin: AmazonFeed] Is this compatible MU?

Is Amazonfeed compatible with MU?

I try it with MU, but it seems like when I saved the amazon keyword. and Visit the page there is no Product feeds being displayed.

And when I checked it again the keywords has been emptied.

Hoping for your immediate response.
