As you can see in the client area: it takes up to 72 hours for domains to be visible everywhere. This is due to DNS caching, which is just how the internet works and not something we have control over.
The only “fix” is to just have patience, as it will fix itself over time. Just don’t start messing with your domain’s DNS settings, including moving it between accounts, because it will only take longer that way.
