Thank you so very much, the decision to keep 1 custom domain in Tier 3+ was strategic decision by Appsumo team to balance both types of buyers - solo & agency owners. If we add custom domains same as total number of workspace then price would be higher and that may be bit disappointing for solo buyers, hence Appsumo team thought of keepnig extra custom domains as add-ons so that agency owners can buy as per their needs. I am keeping this suggestion in mind and see what can we do, I will talk to Appsumo team about it. Thank you so very much.
