Harmony Ultimate doesn't like LG B9
I'm not having any luck getting my Harmony Ultimate to control my LG B9 TV. The remote worked flawlessly with my older Samsung, but I've tried editing my Activities by just deleting the Samsung and adding the LG, and I've deleted the Activities entirely and set up new ones, but nothing seems to work. The TV is connected by HDMI to my Yamaha AVR, by a Cat5e to my WiFi router, and by a digital optical cable to the corresponding port on the Yamaha.
Wondering if the power-up order for each device could be a problem.
Any insights would be greatly appreciated.
