-If every hostname on a non-wildcard certificate is [proxying traffic](/dns/proxy-status/) through Cloudflare, Cloudflare can automatically complete DCV on your behalf.
+If every hostname on a non-wildcard certificate is [proxying traffic](/dns/proxy-status/) through Cloudflare, Cloudflare can automatically complete DCV on your behalf if the DCV method is [HTTP](/ssl/edge-certificates/changing-dcv-method/methods/http/).
 
 This applies to customers using [Universal](/ssl/edge-certificates/universal-ssl/) or [Advanced certificates](/ssl/edge-certificates/advanced-certificate-manager/).
 
 If one of the hostnames on the certificate is not proxying traffic through Cloudflare, certificate issuance and renewal will vary based on the type of certificate you are using:
 
 * **Universal**: Perform DCV using one of the available [methods](/ssl/edge-certificates/changing-dcv-method/methods/).
 * **Advanced**: In most cases, you can opt for [Delegated DCV](/ssl/edge-certificates/changing-dcv-method/methods/delegated-dcv/), which greatly simplifies certificate management.
+
+If you're using [TXT](/ssl/edge-certificates/changing-dcv-method/methods/txt/) as DCV method for Advanced certificates, you can look into using [Delegated DCV](/ssl/edge-certificates/changing-dcv-method/methods/delegated-dcv/) to help.
