Hey there
As this documentation describes, it is possible to set up a custom domain. But it also says, that this feature is only available in Pro or Enterprise plans. As far as i know these Plans are no longer available. So my question is if the cusom domain is available in the free plan or only accessible if i purchase a whitelabel plan (or not available anymore)?
Connecting a custom domain is only available on a Custom Plan. You would need to get in contact with our sales team at licensing@8thwall.com to get access.
