The first time you set up your speaker, the app is required to download the necessary software. After the first update, the speaker will automatically download new software with important bug fixes and new functionality as it becomes available (unless you disable AUTO-UPDATE FIRMWARE from speaker settings).
The auto-update feature happens periodically in the background — there’s nothing you need to do. You may notice the lights glowing on top of the speaker or it making the power-on sounds after a new update has been installed. We recommend keeping the auto-update settings enabled, but you can disable it at any time from Speaker Settings (the gear icon on the top right of the app).
