Fire TV Remote or Game Controller not Detected

I purchased a 2015 FireTV 4K to run the Tablo app on my TV. I’m using a Logitech Harmony Home Control universal remote - its connected via bluetooth to the FireTV,

Anyways, every time I launch the Tablo app a warning pops up - “Fire TV Remote or Game Controller not Detected” - I then have to click ‘Launch Anyways’. Anyone else experiencing this? How do I get rid of this message?
