We’ve read through everything we could find, including the common issues posts in this forum. We originally tinkered with setting branch deploys to individual branches, and then tried switched to ALL, but nothing seems to work.
If using Amazon Route53, which is setup by default if you purchase your domain from AWS, you’ll need to delete the record set within Route53 first. Then, you’ll have to go into the “registered domains” link on the left side menu, and then enter the Netlify DNS nameserver’s.
Simply forwarding your nameservers to Netlify’s nameservers was the mistake we made. You can still get branched domains to work, but it won’t work automatically as described in some of the docs.
