Hello,

You don’t update the domain name from your Rank Math account. Please proceed with disconnecting the old domain name from your Rank Math account.

On your newly changed domain website, please reconnect your Rank Math plugin to your Rank Math account. To do that, navigate to your WordPress admin area > Rank Math > Dashboard > Help, disconnect and reconnect your Rank Math account.

Then, the new domain will show up in your Rank Math account.

Hope that helps.
