Missing DNS Records & Domain Not Showing on Dashboard

I had an existing google domain (before it transferred to Squarespace) that was connected to my Squarespace website. When I look in my Squarspace website settings it says that my domain is connected and it does have a built-in Squarespace domain. When I look in my domains dashboard I see all my other domains (that transferred to Squarespace) except for the one that's connected to my website. When anyone tries to access my website it says: DNS_PROBE_FINISHED_NXDOMAIN or cannot connect to server. 

I tried troubleshooting the DNS Records but when I go to Home > Settings > Domains & Email > Domains the DNS Record Checker isn't there. Similarly, when I go to my Domains dashboard I can't click on the domain settings since the domain isn't listed there. I should say that my website was renewed back in July so it's not a matter of giving the DNS time to load.

Anyone have any idea of how to fix this issue?

Have you tried logging into squarespace with your original Google domains login? 

I am having a related issue - login to Squarespace with my original google ID and my transferred domain is nowhere to be seen.  Just to be sure I tried every other account I have with google, and it wasn't transferred to any of them.  To be clear, even squarespace can see they have registered the domain, but have effectively taken away my control of my own site.
