I use Squarespace to design, my problem started when I put my new domain when suddenly
Squarespace don’t support .mx TLD !!! 
Before paying a webflow plan (because I like the platform) Can anyone help me with this ? Thank you !
Can you use a .mx (mexican) custom domain on Webflow?
Yes.
Hello @RamonCastillo, I think you’re doing something else rather than pointing your domain records to squarepsace. I use .mx domains with squarepsace without a hassle.
Probably you can’t migrate your domain to squarespace, but you can point DNS records to it as you would in other tools like Bubble or Webflow.
I recommend both Squarespace and Bubble, but they are rather different.
Regards,
