Software Updates instructions
Software updates of a PRO extension are made through the Joomla update process.
Once the first installation is done, for software updates to occur, it is necessary that the following conditions are met:
1. You have an active subscription to the extension. If you do not have it you can obtain it by visiting SUBSCRIPTIONS.
2. You have authorized the domain in which you have installed the extension.
3. You have entered the update code obtained in 2 above in the configuration of the extension installed in that domain.

If you do not know if you have authorized a domain, go to My subscriptions and in the subscription of your extension press the button Authorize Domain(s) or See All Authorized Domain(s). That will take you to a page where you can authorize the domain and where you have instructions on how to do it.
