I am using a service name builderall. With using their drag and drop website builder, I can simply point my subdomain A record to their IP eg esp.calvyn.com or I can simply point my primary domain A record to them to build my website there. (no issue for this part)
Wherest they also have WordPress builder, and when I would like to point my domain to there, either primary domain / sub domain, A record is not working. (here the issue)
from cloudflare, I found no way for me to change the NS to others.
from such scenario, is there any workaround?
