Using CEC, the numbers on the YV’s remote control cannot be used anymore to type the login code for a Plex Home user. Only on the screen a numpad is shown, for which you can use the remote control arrow and OK keys to enter the code. This is of course totally undesired, as now anyone can see the code you are entering on the screen. RPI2 and a Samsung UE48HU7500.
Just to confirm that I am seeing the same behaviour updating from 0.6 to 0.7 - number pad presses were definitely working on my Samsung remote on 0.6
I believe this to be a PHT issue because switching users with latest PHT on a Windows machine connected to the same TV via HDMI-CEC adapter has the same issue. Something broke in a newer version of PHT so you will want to report that bug in the PHT forum (if not already reported there).
