Still wondering if there’s a fix for this issue. The issue isn’t just with new CPTs, it’s also with new plugins. When we install a new plugin, Admins cannot see it in the dashboard menu.
We have to go to Users > User Role Editor, select any role and click “Update”. Again, we don’t actually change anything, doing that just seems to force something to refresh that allows Admins to see the new plugin’s settings/menu items.
