Domain Mapping plugin will not redirect properly


I have a user who has been trying to map their domain for over 2 weeks now through the Domain Mapping plugin and GoDaddy. I have logged into their GoDaddy account and the “A Record” is setup properly, but when I add their domain into the plugin setting screen it still goes to an old redirect. I have my own testing domain that I have an “A Record” setup for, and as soon as I add that domain it works fine. It just seems to be happening with her domain. GoDaddy said it’s not on their end, but why does it still redirect to their old website?

Thanks for the help
