Just here to make an observation. We recently purchased the new Roku Ultra 4850R. We’ve had it over a week and all the issues we were having with the Gen 4 Tablo app are no more. I’m not quite sure why. I’m just glad to see this app working like it should (for us) finally.
So if you were holding out for the newest Roku model, I recommend giving it a try. ( also, it is running Roku OS 14 out of the box)
