Hello! Thank you for reaching out. I understand your concerns about the smart TV keyboard not showing the space bar. The button should look like this:
If the on-screen keyboard does not appear when you are searching on your TV, entering a Wi-Fi password, entering a network name, or entering a channel number resetting, then pairing the remote again could help.

If the issue still occurs Please reach out to a moderator in a PM. We would like to obtain a photo of the keyboard you are seeing If one is appearing.
I didn't explain the problem clearly. When I'm in the Pandora or Spotify apps, go to Search, and click the text box, a keyboard does appear on screen but it doesn't have any space key. I just figured out both apps interpret a "." (period) in the text as a space so all is well. Thanks for responding to my original post so promptly.
