Checks / Links, canonical and speed
Public page cannot be cached
The page is open to everyone but is sent with Cache-Control private or no-store (or sets a cookie), so a CDN cannot serve it from cache. Every visit, and every crawler request, hits your server, and cold pages answer slowly.

What to change
Send Cache-Control: public with a max-age (and s-maxage for a CDN) on pages that are the same for everyone, and keep cookies off them.
