Yea, they ARE sticky. If I press another button, the new button will override previous command, but I can't get it to unstick completely, not even using the original remote. I had to restart.
I've updated to latest Flirc and firmware. I added "NVIDIA Shield Game" to my Harmony 700 and mapped it to Flirc using Shield profile. But when I go and use it on my 2017 Shield, pressing the down arrow navigates all the way down, and up all the way up. Couldn't test anything else out because of that. Am I doing something wrong? Thanks
