how do i use the new keynote remote

Update, from Using Keynote Remote

If you have a presentation in Keynote for iOS, you can control your presentation from another iOS device.

2. Open your Keynote presentation on the device you'll use for the presentation.

3. Tap the Tools icon in the toolbar.

4. Tap Presentation Tools.

5. Tap Allow Remote Control.

6. Turn on Enable Remotes.

7. On the device you will use as the remote, open the Keynote app and tap the Keynote Remote icon in the toolbar of the presentation manager. If you're in a presentation, tap Presentations in the toolbar to open the presentation manager.

8. If this is the first attempt to link to this Keynote Remote, tap Continue. If not, tap the Devices button, and then tap "Add a Device."

9. On the device displaying the presentation, tap Link next to the name of the device that will control the presentation. The device name should appear in the Allow Remote Control menu that you had open.

10. Confirm that the four digit passcode that appears on the presentation device also appears on the controlling device. If the passcode matches, tap Confirm.

11. Tap Done on the presentation device to return to the presentation.

You can now control the slideshow on the presentation device by tapping Play on the controlling device. For instructions on using Keynote Remote once you have it linked, see the Using Keynote Remote section below.

So it's not using the "Remote" App, but the Keynote App itself.

If only it worked.

"No remotes were found. Make sure this iPad is on the same Wi-Fi network as the iOS device you want to use as a remote, or connect the devices with Bluetooth."

Same network, all on and ready to receive.

The same iPhone DOES work as a remote for my iMac; just not the iPad Air (all latest OS and OSX).

This seems like a bug.
