I have had two Play:1 speakers for a few years. They have worked great with no issue. I recently purchased a Sonos Move so that I could group them and use the AirPlay2 feature with the whole group. When I play any kind of sound, only the speaker nearest my phone plays. If I move my phone between rooms (in my one bedroom apartment, so not very large for three speakers) the audio changes to play on the nearest speaker after disconnecting and reconnecting AirPlay. But they don’t all play together. I have gotten two to play at once, but only for a few seconds and then one cuts out. I would think if this was a wifi issue that it would be the speaker nearest the wifi that would play regardless of where my phone is?
