I have a playbar and use two play 1’s as rear speakers. When trying to set up with true play the beeping sound comes from all speakers nice and loud and when sitting to do the first step and sound balance it works fine. When I go to the next step of walking around the room and waving my phone I get to about halfway through and everything stops telling me a speaker is lost. I am waving exactly as the video shows and I can hear the sound coming out of all the speakers. I have used true play to set up other speakers in the bedroom and living room with no problems. After twenty tries at this and the same issue arising I am hoping someone at Sonos can help. Thanks.
