Hi Alberto, 
Thanks for contacting Syncfusion support. 
Syncfusion introduced the licensing system from v16.2.0.41 for Syncfusion NuGet packages and evaluation setup. You have to generate the license key and register it when launch of your application as specified in the below help documents if you referring the NuGet packages. 
Below are the User Guide documentation links to register the license in Xamarin application:     
Also, please refer this blog post for understanding the licensing changes introduced in Essential Studio.  
If still facing the licensing message, please share the screenshot of the error, application platform name, and registered license key in your application.

Troubleshoot license errors

Verify your license IP address

Check for connectivity issues

Check resolving and hostname

Check the server time and date settings

Rachel, There is no online system to validate syncfusion license and no internet connection is required.

Please refer to licensing FAQ documentation.
