Our website is on Hubspot CMS, in Cloudflare, we have a cname setup that points to the 6*****3.groupX.sites.hubspot(dot)net the record is set to DNS only.
The issue is page rules do not work (from what I have read in old posts) in DNS only. The option to change that setting is not available for that record though.
So if you go to our site via, https://aopinc.com the page rule will not work that should redirect the request to https://www.aopinc.com.
