DNS Issue Resolution on Squarespace

I need help fixing a DNS issue with my domain on Squarespace. The domain was purchased from Squarespace but the site was built using Google sites. The goal we are trying to reach, is to eliminate the “sites.google.com” address and only operate under the “dot com” domain we purchased.

Ideal Skills and Experience:
- Expertise in DNS management
- Experience with Squarespace's DNS settings
- Problem-solving skills to diagnose and fix DNS issues
