Wait time for subdomains in squarespace

Hi - I was wondering if anyone has experience with registering subdomains when hosting is through squarespace. I’ve followed the instructions and have been waiting for 3+ days. I’ve hit the retry, but ultimately I keep getting “error finding CNAME”.

Is this wait typical?

The site is in the “unpublished” state with squarespace, could that be the issue?

Many thanks in advance.
