Site Design Not Appearing when provisioning new site?

Hi All,

I have recently created a new Site Script and associated it to a Site Design on my Dev Tenant and for some reason I cannot see the site design when I go to provision the site from https://<tenant>.sharepoint.com/_layouts/15/sharepoint.aspx?

It has been 15 hours since I created the site design, does anyone know why this doesn't appear?

Also related to this... How do you hide or delete the Microsoft Site Templates now available to users from the Settings > Apply a Site Template menu item on an existing site? I only want to show the templates available "From my organization".

Thanks for any advise! 🙂
