Disable completely application's license.

I need to disable totally application's license. I expect after this, that users will not be able to activate the app or continue to use trial.

To achieve this I removed the product from LimeLM dashboard. Unfortunately verified trials continue to work event if product was deleted. So users can continue to use the application.

Is there a way to stop application's license completely ?

To stop a user from using a licensed version of your app either revoke the product key or delete the product key. After nDaysBetweenChecks they will no longer be able to use your app.

As far as verified trials, there's currently no way to "revoke" trials.
