iPhone remote not bringing up a keyboard for apple tv
I am trying to use the remote on my iPhone 12 to enter my YouTube password on my Apple TV. Normally when I do this a keyboard pops up to allow me to enter the text. Today no keyboard appears. How can I fix this please? I have updated the Apple TV software, and restarted the iPhone 9its running the latest iOS. Does not work with my iPad either.
thank you for any help you can offer.
