NOTE: I am only concerned with the CNAME record for outreach. I have been trying to get this subdomain to work for weeks now. The way I have added the record is exactly what webflow support has directed me to do.
I also noticed some other records that are set do not resolve. For example, links: links.charliehealth.com.
Could have been DNS propagation after a recent change. I'm showing this resolving just like you mentioned above - to proxy-ssl.webflow.com
