Finally, finally, finally with the latest Feb 13, 2017 update EVERYTHING works perfectly - Flirc + Amazon Fire TV and URC MX-990 !!! Before this latest update, I had tried over a dozen times to get commands working, but would get a couple or a few to work , but never all at the same time. I had tried 3 different remote controls to lean from flir,c but never could get them to learn over to my URC MX-990. I was ready to throw the flirc in the trash can. Along comes this latest update yesterday and ALL is solved! Perfect the first time, EVERY command! Thank you Jason!
