Desktop App disconnect mobile app

Hello,

I come here because i have some troubleshoot on keycloak 22.0.4.
When i open a mobile app session and then i open my desktop app, the mobile session is no longer alive. I precise that OIDC client dekstop use the same flow than OIDC client mobile.

I succeed to solve this problem by use a different browser flow for mobile and for desktop app.

But i would understand why open a desktop app close the mobile session.

Thanks for your replies
