I have a site hosted on Google Firebase, and the domain is hosted with Squarespace. Google requires me to add a CNAME DNS record to the domain on Squarespace so that Google can verify that I own the domain. I've added the CNAME record, and have waited 48 hours, but there's no sign that the CNAME has been propagated anywhere at all.
I had issues getting CNAME records to be propagated by Squarespace before. Is this an ongoing issue?
