Can’t update WPBakery Visual Composer, License Key is required
There’s a difference between getting Visual Composer directly from WP BAKERY or in a theme. If you purchased from WP BAKERY, this means that you own license and you can access WP BAKERY ticket system and get direct and free updates (instant). If you got VC in a theme, that means that theme author has license and only he/she can download latest versions of VC and include it in the theme. You as a theme user, may use Visual Composer free of charge while you use theme that came with VC (because you have license for that theme).
When Visual Composer is included in the theme and you don’t have separate licence for it you need to wait on us to update Visual Composer on our side and push it to you.
