I went to NextDNS. The blocking for adult content and forcing SafeSearch on all browsers is much better. Would never come back to OpenDNS after using NextDNS. costs 2.99 a month, but well worth every cent it costs. Now all adult content is gone, even...

 As you can see, the DNS for the servers is not propagating properly. I am having the same issue; I see it in their DNS resolution. so cant contact them so we are stuck with my kids accessing porn. https://dnschecker.org/#A/208.67.220.220
