I've purchased this plugin and added it to my OctoberCMS project. However, with php artisan project:sync, it tells me that the project is synchronized without pulling down the plugin. And when I run php artisan plugin:install Vdomah.TwoFactorAuth, it says "A product license for "vdomah/twofactorauth-plugin" could not be found". I am running OctoberCMS 3. Can you help?
