I forgot my password and no longer have access to my account's email, can I change the Sonos account my players are 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
Using the Sonos app on Mac or PC: Select Help > Account Settings > Transfer Sonos to a new account
