I converted my site from simple site to multi site and installed the main theme in the network admin. On the main site, the theme works fine but on the sub-site, it ask for license key again and on entering the license key, it says that the key is already registered and cannot be used here.
One regular license allows you to use our theme for a single project/website. For multiple projects, you need to purchase one regular license per domain/website. https://themeforest.net/licenses/terms/regular
