Keyboard for Directtv stream - Help

So, I’ve got the at&t directtv stream.
In the setup there is a spot to pair a bluetooth device.
I do that. The BT KB I have works just fine on my laptop and Firestick.
On the frelling Direct tv thing, most off the letter keys don’t do anything.
H gets me to the home screen. A few others do other stuff.
But when I try to search - the reason I want the KB -
Nada for the characters. But the numbers will put up some letters and numbers.
Making me nuts.
Any ideas?
All the Best, Jeff
