@OldDogCan - yes my 218 is up to date - and I never saw the magenta light once whilst playing Roon! Always green or blue so I just assumed it was working OK. Plus there was no mention of magenta in the original manual so had no reason to think it was wrong. Is magenta therefore preferred over green?

@ChrisLayer - thanks for the info. Am curious - what light do you get if you don't link zones with a renderer? Blue/Green?
