I have no configurable apps. It happened after the 12/8 update, and I've been waiting for them to come back. I thought maybe they had been all removed and moved to the new Solutions app, but I still see people using them.
When I hit "Create" under the Content menu in AGOL - the option for Configurable Apps is missing.
When I click on a map, there is an option to create a Configurable App, but there are no apps in the gallery.

I need a few different templates for a project and I cannot access anything.
Have you checked your configurable app group in 'Organization', 'Settings', 'Groups'?
I had a similar problem where I couldn't see the new configurable apps. I hadn't allowed my configurable apps group to share the Esri defaults.
