I have a public app. When I add a tab to the Menu, the Sign In option shows up in the Menu. If I don’t add any tab to the Menu, I see just the info icon. I have not configured any sheet for collecting user details, nor associated a sheet to the Sign In option. I would expect the Menu to not give an option for signing in to the user even when I add tabs to it. It looks like a bug. But not if this is intended.
