Can't create new user from Auth0 dashboard

All of the sudden, I’m not able to create a new user from the dashboard. I get "Error! Sandbox Error: App "all Applications’ cannot be used for user registration.

I figured it out. I had an action that was only allowing a certain application to sign up. I had to include “All Applications” in the whitelist.

Facing same issue here. Help is appreciated.

@Marshall155 ,

Could you provide a screenshot of the error and DM me the name of your tenant? And have you got a chance to check the Actions and errors in the tenant logs?
