Lost access to organization that published my VS Code extension

Thanks for reaching out.

If you’ve lost access to the organization that owns your extension, you’ll need to work with Visual Studio Marketplace support to regain control. Here’s what you can do:

• Go to https://aka.ms/vsmarketplace-support and submit a ticket.
• Include:
  • The extension URL: https://marketplace.visualstudio.com/items?itemName=xvyslo05.cypress-open-testcase
    • Your current publisher ID and any proof of ownership (e.g., GitHub repo link, previous publishing history).
    • If the original organization is inactive, request an ownership transfer to your personal publisher account.
    • After ownership is restored, you can generate a PAT and publish new versions.

Unfortunately, there’s no way to claim the extension without Marketplace support intervention. They handle verification and transfer requests.
Let us know if the issue persists after following these steps. I’ll be happy to assist further if needed.
