Hello, I currently have a domain purchased through Domains.com, and I also purchased Google workspace through them and have my custom email set up. I was originally attempting to create my website on Wordpress, and my website is currently by Hostinger. I have a Wordpress theme installed, so if you visit my web address there is a site up, but it's not completed. I would like everything to be created through Squarespace now, so can anyone advise if it is a straightforward process to 'disconnect' from Hostinger/Wordpress? Also, if Google workspace was purchased via Domains.com is it still going to work independently of that, if I were to connect/transfer my domain to Squarespace? Last question: is it worth transferring the domain to Squarespace, or should I just stick to connecting? Thanks in advance! Nina
