Nameservers updated to Cloudflare but still not active / in pending status

I updated the nameservers of my domain with my registrar to the two Cloudlflare nameservers I was given to utilize with CF DNS service. The update is reflected correctly in the WHOIS as well as with the registrar. But the domain is still showing as not active and in pending status.

What else do I need to do?

What is the domain name?

Apparently the issue was that the registrar must set the NS to only Cloudflare’s NSs. I had the domain NS pointing to both Cloudflare and another third-party NS. When I took off the other two and only left CF’s two NS servers, the issue resolved itself.
