Keynote remote control seems to not work on iOS 17.6.1

Following the Apple provided steps, when I am trying to connect a remote controller (in my case an iPhone 11 with iOS 17.6.1) on my iPad (also iOs 17.6.1) the phone will not appear as a remote controller. The Phone WILL remote control keynote on my Mac computer running 12.7.6. The iPad will NOT connect to be a remote controller of the Mac.

Is there some other setting needed on the iPad that will turn this much wanted feature on??

Thanks

John./
