Questions About MCP Server Changes and ChatGPT App Re-submission
OpenAI Developer Community

Hey folks, good question, that part can feel a bit unclear.
Even for backend-only tweaks or small schema or widget updates, it’s still treated as ongoing maintenance. Once your app is published, that version is locked.
So to make changes, you’ll need to:
* Create a new draft version of your existing app (not a new app)
* Resubmit it for review
Each resubmission starts a new review cycle. It helps a lot to clearly list what changed in the release notes so reviewers can quickly understand the update.
You can find more details here: Submit and maintain your app.
