Just bought the U1. Successfully set it up to control my Onn Qled TV, Samsung Soundbar and Apple TV 4K. One problem I'm having is that it won't power off the Apple TV which is an Apple thing not the remote. Googling the problem, I found out that on the Apple TV remote long pressing the Home button brings up an option to put it to sleep but long pressing the Home button on the U1 does nothing. Has anyone found a fix for this or another way to get the Apple TV to power off?Found a solution, Added the Apple TV 4K as a bluetooth device.
