Before we dive into how DNS works, the first thing we will say is BE PATIENT!
Don't keep refreshing your browser every minute or every hour!
If you see your old website, then refresh and see your new website, then refresh again and it goes back and forth, this is normal and still part of the site propagation!
Again, be PATIENT! Don't send us emails, or your marketing team or your website company using CMS Max thinking something is wrong.
This process can sometimes take 5 minutes, but also it can take up to 24 hours! If it's been more than 36 hours, then you can contact us.
Please watch this video below on a little understanding of how DNS works.
