Disappearance of Sign In Button

Why does the Sign In button disappear when I assign a sign-in action that has its privacy set to public with the ‘Optional sign in - Users in the users table’ option? Did something get overlooked?

Are you viewing as a user who has signed in already?

No, I view it from the fake email for testing purposes.

Fake or not, aren’t you technically viewing the app as a signed in user? What if you view as “anybody”? What if you view the published app?

You’re right Jeff.
Thank You very much.
