It depends on the support package you purchased for every item.
By default, we provide support for 6 months, but you can extend this period by purchasing a support package. Note that you will not be able to submit a support ticket for an item if the support period has ended!
In order to purchase a new support package, please visit the item’s page on CodeCanyon or ThemeForest and purchase an “Extended Support” license.
Check “Extending and Renewing Item Support” page on Envato Market for more info.
