Tablo app not offered Fire TV 2nd gen

Good day folks!
I have a Fire TV Stick and Fire TV 4K unit. Had no problem downloading and installing the Tablo app on the Stick but it’s not offered for the 4K unit as best I can tell.
Is this a compatibility issue or am I missing something?
Thank you for your time and expertise.

Are you talking the 2nd Gen Fire TV box or the new 2017 Fire TV pendant?

Either way there should be an app available.
