Not sure what happened. Everything with my Amazon fire tv, flirc, and harmony 700 has worked fine for months. Suddenly today I noticed the ok buton stopped working in kodi. I tried rebooting the amazon fire and got back to the Amazon OS but the ok buton doesn't work there either. I tried plugging the flirc dongle into my windows laptop with kodi on it and the ok button functions as it should. Why would the ok buton work on windows but not on the Amazon fire? Any help or advice would be greatly appreciated.
