hello

We are trying to use IsFeatureEnabledEx to check if a certain feature is enabled for a license. We can see on the QLM Console that the feature is enabled, but the function returns false. Working on this for a few hours now. 

 

In addition, we tried lv.QlmLicenseObject.GetFeaturesAsString but it returns empty string. 

Any clue what the cause might be?

  IsFeatureEnabledEx will return valid results only after a License has been successfully validated.

  This is described in the documentation: https://support.soraco.co/hc/en-us/articles/207611713-QlmLicense-IsFeatureEnabledEx

  I understand that. But looks like if we change the on/off of a feature on QLM console, next time the program runs the IsFeatureEnabledEx function, it returns the old feature value (!). Is the first results cached somewhere and always used?

  Features are embedded in the Computer Key. In order to get the new features, you need to reactivate the license to get a new Computer Key. If you are using the LicenseValidator class and enable server-side validation, the LicenseValidator.ValidateLicenseAtStartup function will automatically reactivate the license behind the scene if it detects that a feature has changed on the server.
