Sorry for the problem with the WordPress child theme page links. It's possible that the issue is due to the developer is working with the site. Please double-check with your developer to see if the option to display the maintenance page is working once they have completed their work. Otherwise, please provide us more information about your site (site URL, version of WordPress, etc. ), as well as how you are implementing the site maintenance page (as there are multiple ways that this option can be used).
I hope this helps to answer your question, please let us know if you require any further assistance.
