The free app url has the word sandbox

Forgive me for asking this, but i was using mendix a longtime ago. But again i started recently. I noticed that the free app cloud url has the word 'SANDBOX'. Formaly there was no word like that. Is there a method to remove this?   Regards

I dont think you can, it's one of the characteristics of the Sandbox. If you upgrade to a paid plan, this will be gone and you will have the option to link a custom domain for example.
