I’m happy to say that after a few hiccups with the Tumblr Domains thing, Tumblr Support has been very helpful in getting me up and running with transferring my domain over. They were even able to get the verification thing worked out, so my domain won’t be blocked for not verifying.
My next step is working on getting my email provider to connect to the domain since Tumblr doesn’t do email with the domain stuff. Just FYI for anyone interested in having a Tumblr Domain where you want to use email. I’m planning on using Protonmail’s custom domain option to handle email for my domain. However, I can’t seem to enter the DNS records I need to make it work at the moment. Once I have a fourth DNS record setup, I can’t add anymore. Anyone else seeing this that also have a domain hosted by Tumblr??
I’ve reached out to Tumblr Support again for help. We shall see how this goes. I’m optimistic there is still just a few weird things happening on their end with this new feature.
