According to our rules, we always allowed to use a Regular license for a single project. For multiple projects, you need to have one license per website. You can find this information in our documentation and in numerous comments and support topics. 3 activations meant 1 staging, 1 production, and 1 extra for cases when customers forget to deactivate the license before uninstalling the theme. Now we remove this 1 extra because customers think that they can use our theme for 3 different projects.

Kind Regards
