IPad OS 16.1, Playgrounds and input fields

I have installed the latest beta on my iPad , iPadOS 16.1 (20B5050f)

On running in app in Playgrounds that has a TextField, external keyboard input do not seem to be working.

Tapping on the Text field inserts the cursor but no text can be entered on my external keyboard. (TextEditor field also do not work)

Tested with both a Smart Keyboard and a Magic Keyboard.

The keyboard works to enter the code in playgrounds, so it is not a keyboard connection issue.

Disconnecting the keyboard, the onscreen keyboard is displayed and works correctly.

Is this a Playgrounds issue or an iPadOS 16.1 issue or a compatibility issue with Playgrounds & iPadOS 16.1 ?

import SwiftUI



struct ContentView: View {

    @State var field: String = "Test input"

    

    var body: some View {

        VStack {

            Image(systemName: "globe")

                .imageScale(.large)

                .foregroundColor(.accentColor)

            Text("Hello, world!")

            TextField("", text: $field)

                .frame(height: 100)

        }

    }

}
