The app finds no speakers
Your iPhone, iPad or Mac has to be on the same Wi-Fi network as your Sonos speakers, and Amuso needs Local Network access: on iPhone and iPad, in Settings, Apps, Amuso; on a Mac, in System Settings, Privacy & Security, Local Network.
A song does not play on the speakers
Your speakers play from Apple Music themselves, so the Apple Music service has to be signed in to in the Sonos app, with an account that has an Apple Music subscription.
No Dolby Atmos or lossless
Dolby Atmos plays on speakers that support it, such as the Era 300 and the Arc, and only for albums released in Dolby Atmos. Amuso shows a badge on the albums that have it.
Restoring the unlock
In Amuso’s Settings, choose Unlock…, then Restore Purchase. The unlock works on every device signed in with the same Apple Account.
How Amuso handles your data is in the privacy policy.
