Why can't I purchase it here I understand that you want more support on Patreon but if someone just wants to develop & your making it either Patreon or no plugin it becomes gate keeping & adding a limit that you already don't have when we can purchase it on here.
Just make a second bundle or allow us to buy it on here especially since if you take down your Patreon or its no longer viable we won't be able to redownload the plugin
