Some users can not activate HomePod
Some owners of HomePod have experienced problems with the activation of the speaker. Typically, the problem is characterized by a white screen installation with no identifying characters and the ability to perform an action or a “Setup Failed (-6722)” error.
Analysis of the situation showed that the failure of the installation can be caused by a number of factors. Among them: the outdated version of iOS (HomePod works only with devices based on iOS 11.2.5 and newer), disabled iCloud keychain or two-factor authentication, as well as missing applications “Home” (with which it is configured) or the application “Music”.
If you are faced with the inability to activate HomePod, Apple representatives recommend making sure that you have met the requirements described above. As a rule, noted in Cupertino , their non-compliance is the primary cause of errors.
