If every single button is black, sounds like someone did that on purpose. If it’s a recent change, reload from a backup taken before that happened. If they have always been all black, and there’s no reason for it, you can go page by page selecting all buttons and changing the background color to default - or you can start over by creating a new user. Videos in the Lilly’s Voice library can show you how to do all those things
