My Nvidia Shield TV is really new with the almost newest firmware and the newest Prime app. The Prime app don't show channels on the Nvidia Shield mainscreen and not shows channel settings for Prime. Prime is not shown there! I rolled the Prime app back to last version, rebooted the Shield. Nothing helps! This is by the way a common problem for many users (international!). See google and several forums.
How to get this solved? I don't like to the reset the Shield. All other apps working and shows channels.
