My system is working fine, and I can control it from my Mac, iPad or iPhone. But on my iPhone, there is a banner saying "Sign in to use new features. Sign in". When I try to sign in, my credentials are rejected "The email and password you entered did not match our records. Please try again". The email and password work fine on my Mac and iPad, and on the Sonos site.
It's not a big deal, because everything works, and I can change settings using other devices. But is there some secret way to get an iPhone to accept my credentials?

Your system is probably registered to a different email. Luckily, you can transfer the account your Sonos system is registered and linked to.
Using the Sonos app for iOS or Android: Open the Sonos app. From the More tab, tap Settings > Account Settings > Transfer Sonos to a new account
