Magic Keyboard is not working with latest iPadOS 18 Developer Beta 1. It worked previously. I’m sure you will update it, just wanted to leave feedback on it. Mouse works, but has the apple mouse curs...
Experiencing the same issue. Magic Keyboard (or any Bluetooth keyboard) will work if you turn ON the on-screen keyboard, but that will obscure the bottom of the screen. Not ideal. Looking forward to an update.
