If I already logged in from one app(sub domain) why auth0 redirects to login screen for another app (sub domain)

[subincv]

Thanks for the document but it not helped in my issue, I am not facing issue while login and logout.

There are 2 client app both are on same host domain but different sub domains, when user already logged in one client app it still ask for login in second app, it should be auto login because user is already authenticated.
