Might this be a possible glitch?

I haven't seen that, but a couple of other users have mentioned one. Usually with such a message there should be some way to accept the message or otherwise close it out. Try using the directional pad to move around in the message. You might need to scroll it down to the bottom to find the accept button.

Cherie_  I had a brief message pop up on my Apple TV connected to a new Samsung 4K TV.  Is it possible the message is from your TV and not from Roku?

Hey there, Cherie_!

We'd love to hear about your concern.

Could you provide a photo of it so we can take a closer look? 

It would be much appreciated if you could provide us with this info.
