The failure

What the user was trying to do

Collect pricing from a vendor dashboard that requires interactive login, then summarize differences by plan tier.

What happened instead

The agent revisits already-completed pages and loses the plan state after login.

How to reproduce it

1. Start a browser task that requires login halfway through. 2. Approve manual login. 3. Ask the agent to continue with the original extraction task. 4. Observe whether prior context remains intact.

More details

Environment details

Browser session in desktop app, SSO login flow with redirected tabs.

Evidence notes

Video capture shows the agent returning to the landing page instead of the authenticated dashboard after login.

I could not reproduce this in a non-SSO flow. It may be specific to redirected login tabs.
