Shared Project link redirects recipient to ChatGPT home page instead of opening the project

Issue:
Shared Project link redirects recipients to their own ChatGPT home page instead of opening the shared project.

Sharing setting:
Anyone with a link

Expected:
A logged-in recipient should be able to open/join the shared Project.

Actual:
The recipient opens the Project share link but is redirected to their normal personal ChatGPT page. The shared Project is not shown.

Reproduction:

  1. Create a ChatGPT Project.
  2. Set Share → Anyone with a link.
  3. Copy the Project sharing URL.
  4. Open it using another logged-in ChatGPT account.
  5. The link opens the recipient’s normal ChatGPT home page instead of the shared Project.
