Via Gamepad I can move within the Miiverse and can switch to and from the Wii U menu, but I can't navigate it. Also, if I'm using the Internet browser via is the Gamepad, all of a sudden it might not allow me to click anything, yet I can navigate with buttons.
I think there recently was a Gamepad update and these bugs have been occurring since then. Does Nintendo have a bug list or should I better submit a supprt ticket?
