Hi, since your new 2022.4.28, Major Update all is working now. Thanks a lot for your help

Hello, thanks for your answeer. I followed your instructions, but the result is still the same: all self-learned buttons are working, exception: the vol+ / vol- I tried to repair them a couple of times. What I have found out so far is, that on the original remote I have to press the vol+ / vol- a little bit longer then the other buttons (ca. 1 sec.), it's not a battery problem of the orginal remote ;-) Could I add a delay for the vol commands in the X1 so the the X1 remote can send out the signal a little bit longer? With my old Logitech Harmony One all is running fine.

Please add: Nubert / NuControl (Pre-Amp) Learning function did not work for all buttons, especially Vol+ and Vol- (learning seems to be successful but the buttons without a function, no volume control)
