Unity UI: Scaling a 16:9 setup down to4:3

Ayep- I built my app for Android and iPhone and have realized that I now need to support the iPad’s 4:3 resolution as well. As you might expect, items anchored to the top of the screen are getting cut off, assets no longer fit properly etc.

Is there a best practices for taking a 16:9 UI and pulling it down o 4:3?

Anchor to corners, and do a screen resolution check.
