While my system was “upgrading” to the new firmware one of my Play:1 surrounds failed to update (that's ongoing saga story in itself). I've swapped it for another one, but I now need to retune the system. To add to the disasters that Sonos have inflicted on us all, I now find the old iPhone 6s I kept just for trueplay is no longer supported.
I'm not an Apple user, so before I go to the expense of buying a cheap used iOS device, can someone confirm that trueplay actually works with the new app and firmware?
