I have a third party domain on my site which is connected correctly and seems to be working fine at first. However Ive found that when I use certain links within my site, the page that loads next will use the built-in domain that Squarespace assigned me. It then uses this domain in all the page url's after this, until I type my primary one back into the browser. I had thought that the built-in domain was just used for editing in the back end.
Has anybody experienced this before or know what I may be doing wrong?
