Dynamic URL slug
This setting is for providing the slug to be used for social media profiles. Eg.
https://www.mydomain.com/go. This will be what users visit and the WordPress install handles the redirection to the actual intended destination.
This setting is for where, inside your WordPress install, the Dynamic URL should go to. If this value is set at all, it will be where the user is sent to.
This setting is for where to send the user to, external from your WordPress install. If the "internal redirect" value is set at all, this value will be ignored. If this is the only value set, this value will be where the user ends up at.
This is going to be for the license key provided by Pluginize and your purchase of InstaGo. Without it set, you will not receive update ability without this and the email saved.
