Need Help Connecting Custom Domain & Fixing SSL Error on Shopify

I just bought a custom domain name from GoDaddy, and I’m trying to link it to my new Shopify store. I followed a YouTube tutorial, but every time I visit the URL, it says "Connection Not Secure" or gives me an SSL pending error. I have a marketing campaign launching tomorrow morning and need this fixed immediately. ​Key Responsibilities ​Log into my GoDaddy and Shopify backend to correctly configure DNS records (A Record and CNAME). ​Ensure the old .myshopify.com domain correctly redirects to the primary custom domain. ​Troubleshoot and force the SSL certificate to provision so the store shows the secure padlock icon. ​Requirements ​Must be able to start right now. ​Proven experience handling domain migrations/DNS settings (GoDaddy, Namecheap, Google Domains). ​Quick communication via chat.
