The notice:

Cloudflare Add-on is currently enabled. Configuration of the CDN settings is not required for Cloudflare to work on your site.

is now displayed when:

1. The official Cloudflare plugin is enabled/Cloudflare account activated - regardless of whether Cloudflare APO is enabled.
2. The Cloudflare plugin is deactivated and our Cloudflare add-on is enabled - regardless of whether "Cache Everything" is enabled.

This matches what was happening with 3.13.4 as far as the enabled Cloudflare add-on goes.

Customers that are using Cloudflare even without APO or "Cache Everything" don't need to add anything to the CDN tab.
@piotrbak Should we cover cases where our add-on is disabled but Cloudflare is used on the site?

@vmanthos What we have now is good from my perspective
