I’m seeing the APO headers from the plugin, so APO is not activating, I suggest you open a support ticket and post the ticket number here.
To contact Cloudflare Customer Support, login & go to https://dash.cloudflare.com/?account=support and select get more help. If you receive an automatic response that does not help you, please reply and indicate you need more help.
cf-edge-cache comes from the Cloudflare Plugin, and that’s usually what APO looks for to activate.
Cache-control will tell Cloudflare to not cache that page. I don’t know if APO will override that header.
You still need to contact Support to activate APO, though.
