Does the warning on the domain mapping plugin essentially mean not to use "mapped domain"

Warning on Domain mapping plugin site: If in the previous steps you chose “Mapped Domain” as the method for accessing the admin area and the domain being mapped is either not resolving to your server yet or not resolving for another reason other than DNS propagation then that admin area will not be accessible until the domain name has resolved correctly. Choose another option if this bothers you. :slight_smile:

Adding a domain name which is not resolving correctly in this instance will make that admin area inaccessible. Honest, we warned you!! :wink:

Also, I had to send an email about my other domain mapping plugin question because I sent a screen shot of my wp backend issue.
