Custom 404 page

Feature: 404 page custom behaviour (redirect or custom page)
Need an option to customise the 404 page behaviour just like error page customisation at tenant level.
Use-case: or https://custom-domain/asdf gives a 404 blank page, which doesn’t have option to customise or redirect.

Thanks for the feature request. I can confirm the example you gave are not affected by the Customize Error Pages.
