Hello Finally I have the new Sonos Arc and now it appears that I now have to have 2 apps, and it can not work with my other Sonos boxes including the 5 can not reach .... why does this not work together? ridiculous, I had a nice "round" system at home with the playbar and 3 x Sonos 1 and 2 x Sonos 5 and now they don't work together anymore! I have an old Mercedes from 1987 that can still be serviced by the dealer and all parts can also be ordered, see that's service! nor is it fair from Sonos to sell the Arc without telling you that your "old" systems don't work with it! and that your (expensive) Sonos 5 are worth nothing, how do we solve this? free new 5 boxes? or just make an update that everything works together! it is shame!
