You have adjusted and simplified your pricing model a bit lately, but there is still some confusion, especially for new users.
In the billing FAQ it says that the Nimbus Business base package "includes" five users, which would mean paying for at least 5 users (5 x $6 = $30 if paid annually). Under "Pricing" you can see a "2+" next to a person icon, which obviously means that you have to pay for at least 2 users (2 x $6 = $12 if paid annually), no matter if you have created 2 users or only one.
It's probably the case that even if you don't need another member and only want to use some of the benefits of the Business subscription (e.g. unlimited workspaces or blocking blocks), you'll still have to pay for at least 2 members, but other than the "2+" it doesn't say anything about that in the text.
Also it is not even quite clear if the owner of the account, who is admin, is considered a "member" or not.
Honestly, I'm not quite sure myself what exactly applies now. Probably the texts of the FAQ have not been corrected completely, I dont know. In any case, I think absolute clarity should be established here, as this is about paid services.
