License Key Activation (Free to Paid) – SST Pro Plugin

This issue usually occurs when users try to activate the license key in the free version of the plugin.

After upgrading to the paid plan:

Download the Pro version plugin ZIP from the order confirmation email.
Install and activate the Pro plugin on your website.
Once the Pro plugin is active, activate the license key.

⚠️ Note: Activating the license key in the free version will not work.
