New Magic Keyboard (2020) with iPad Pro (2nd generation) 11-inch - keyboard keys not working

I ordered the new Magic Keyboard for my iPad Pro 11-inch. Attached the iPad and the keyboard keys are not working. If I plug in the USB-C to the Keyboard it shows charging, so that functions. But, none of the keys or trackpad show on the iPad screen.

• I've powered down and restarted
• Wiped the connection dots
• Connected the iPad to my old keyboard, which still works
• Checked for software updates, all up to date

Appreciate your help!
