1, application setup problem. Smart island display needs to ensure that the option to display lyrics is enabled in the mobile phone application. When the smart island is not displayed, you need to find the option to display lyrics in the settings menu of the mobile phone application and turn it on.
2. Music copyright issues. The song has no lyrics, or the copyright owner of the song is not authorized to display it on the smart phone island. In this case, the lyrics option is turned on and the smart island will not be displayed.
3. Equipment compatibility. Music listening software does not support the smart island function in mobile phone applications and is incompatible. Need to update the mobile phone application to the latest version, or contact Apple Customer Service for help.
