Custom Admin URL issue

If I give my GRAV site a custom admin URL (e.g. yoursite.com/grav/hello) then update the admin. It resorts back to the default Grav admin URL (e.g yoursite.com/grav/admin). Is anyone else having this issue?

Are you copying the config file to your user/config/plugins folder? That's where all customized plugin config files should live so that they don't get overridden by an update. You only have to include changes in the copied file. The system merges the plugin's config with your config to form the effective config.

Thanks! That's the step I forgot.
