i have CNAME record in DNS that points cpacer to ext-cust.squarespace.com on the squarespace. on the squarespace side i have Domain primary for muni.org that is only validated partially for verily.squarespace.com because I can't point www or @ to squarespace. another domain connection for cpacer.muni.org. is fully connected on the squarespace side. what happens in that squarespace does to www.muni.org and/or muni.org and not cpacer.muni.org. what am i missing here.
