Wireless
Why this works:
The Home App is the central point of connection between your iPhone and your HomePod. If your HomePod has become unresponsive to your iPhone’s prompting, or it’s encountering some other connection malfunction, temporarily removing the Home app from your iPhone might give your devices the chance to form a clean connection.
Pro tip:
If you keep any of the information in your Home app protected by a password or code, you may want to write that information down somewhere else. It’s possible you’ll need to manually reconnect your Apple account and HomePod to the Home app when you download it again.
