JBL Link 10 relies on automatic, over-the-air (OTA) firmware updates via the Google Home App to function properly

Technically, there is no "Check for Update" button in the Google Home app for the Link 10. However, you can try these steps to trigger the process: Reboot the Speaker:

: If the speaker is unresponsive or missing updates, hold the Mute button for 13–15 seconds

Plugged Into Power: Keep the speaker connected to its wall charger.
