As a side note, email forwarding in Squarespace to gmail accounts does not seem to work. I did not come over from google domains but created my site on squarespace and used the email forwarding feature to set up email to 3 different gmail accounts. They did not work. I've tried support but have hit 3+ weeks of "someone will get back to you." Yesterday I added an old yahoo email address and it works flawlessly. So it appears email forwarding to gmail accounts doesn't work.
If anyone has it working - domain on Squarespace, not google, please speak up. and how did you get it to work??
