Authentication state mismatch prevents repository submission

[seva9523]

Hi, I’m trying to submit seva9523/EvalRepro through https://www.goodfirstissue.org/submit-repo.

Expected behavior

After signing in with a GitHub-connected account, the repository preview/submission form should recognize the authenticated session.

Actual behavior

The site header shows my profile avatar, but clicking Preview returns:

Sign in to submit a repository.

Steps to reproduce

1. Sign in through the GitHub-connected account flow.
2. Open the repository submission page.
3. Enter the public repository URL.
4. Click Preview.
5. The form reports that sign-in is required.

Troubleshooting already attempted

• Signed out and signed in again.
• Cleared site data/cache and performed a hard refresh.
• Retried in fresh tabs.
• Confirmed that the repository is public.

Environment: Chrome on macOS, 15 August 2026 (Europe/London).

This appears to be an authentication-state or callback mismatch between accounts.goodfirstissue.org and www.goodfirstissue.org. A cropped screenshot is attached; unrelated browser and personal details were removed.
