I have a question about the CNAME/custom domain feature for the Tier 3 plan. I noticed there's a $9/month add-on option for custom domains, but I've also seen mentions that CNAME functionality is included with Tier 3. Could you please clarify if purchasing Tier 3 already includes the custom domain/CNAME feature, or if I would need to purchase the add-on separately even with a Tier 3 subscription? I want to make sure I understand the full pricing.
