I highly doubt the issue reported in
has been resolved from a technical implementation. If it has been great.
Today my housemate encountered another unexpected behavior. Their Apple Music account needed reauthorized. They clicked the right places and provided Apple password. The screen said the password was wrong, even though they were sure they used the correct one. The cancelled the re-authorization process. At this point their Apple Music account had in fact been reauthorized for use on Sonos (as evidenced by being able to browse their content from Apple Music within the Sonos app). But, the Sonos system had replaced their previously input account nickname with the First and Last name on their Apple Account. Clearly this isn’t intended or wanted behavior-- users don’t like to fuddle with things just to have them undone by some broken software workflow. We set the nickname again, but this doesn’t have to stay broken.
