Why is my newly added DKIM key not showing in the portal?

DKIM keys are updated differently than SPF and DMARC records in the BP Portal. 

1. We receive failure samples for that domain that include that selector.
2. We receive an RUA report from Google that references the selector (selector is not a standard RUA report detail, but Google does include them).
3. The DKIM selector is manually added EasyDKIM page.

Therefore, the DKIM key will not show up in the portal until these criteria are met, and the key is being used by the product.
