Hello, Where do I contact and how much do I pay if I bought the highest tier in Oct of 2024 and it seems like the only thing missing is the Custom Plans for Agency Clients, right? or did I get that as well? Please let me know how much is required to upgrade to that level as I think I am in one of the top 3 tiers of your current version but I am not sure wich and need to know if we have that last feature or not and how much the difference is. Thanks.
