Nothing you need to do. It'll be available again.
Maybe you're thinking there are some new features in OS 11 you want. Don't. The features don't come with OS 11. They come later. Roku is rolling out features separate from the OS rollout. I've had OS 11 on one device since the day the update was announced, and the features haven't rolled out yet. And not all of my devices have the update yet. It'll come. Just be patient.
