When logging in via a web browser, X sessions are created that block access for other users (old licensing method) - for support

The issue is caused by HTTP authentication (https://localhost:5434/admin/auth-settings) — when using HTTP authentication, the browser creates a new session with each action. The solution is to stop using HTTP authentication (configurable at the URL mentioned in the previous sentence) and to close the current browser window (so that the individual sessions are terminated).
