Duplicate App generates 'not found message' when link copied

I am duplicating an app using the copy sheet function and the app creates successfully, but when I try to share the link it doesn’t work and renders a “not found” message in the browser. This is not unique to the app I created, it also happens when I use the glide templates. Any help would be appreciated.

Apps are created in draft mode now. You need to publish first in Share app.

Hmm okay, it seems you are already sharing. We will take a closer look.
