Unable to register .us domain

I have been unable to register my .us domain for several weeks now. I have successfully enabled DNSSEC and added my address to my DNS txt record. It took about a month for this to reflect on my ENS domain search listing…

Now I am stuck on step #3: “Submit Proof”
“You are the owner of this address. Add your domain to the ENS Registry now” appears, and the “Register” button is highlighted in blue. However, clicking register provides no action or response, and nothing changes on the page. Same issue on mobile as well.

(.us domain, coinbase wallet, chrome browser & coinbase wallet extension)

Issue still persisting… any thoughts?
