Hey @dfahey37. To help the neighbors in the Community see what is happening for you, could you please grab a picture of a side by side comparison of how the view looks on your Firestick vs the Ring mobile app?
Did you ever figure this out? Seems to be tied to the camera name at top, and "push and hold to talk " text at bottom when viewed on tv fire firestick. It would be nice to remove the grey bars.
