Universal Login - multiple connections logs you out when logging in another connection

We have a setup where one application1 is using connection1 and another application2 is using connection2 all under one Auth0 account. We want to achieve a situation where a user with different email/password combinations should be able to sign-in to both applications at the same time in one browser. What is happening now is that when a user tries to switch from application1 to application2, they have to always re-login when switching between the two. How can we achieve a user in one browser signed into both applications that is under one Auth0 account?
