Template/Widget changes not reflected in GPT App after MCP redeployment

Hi OpenAI Team, when I redeploy the MCP server, the MCP tools are correctly invoked by the GPT. However, frontend updates (Templates with ui://), specifically widget changes in my case (single bundled HTML files built with React/Vite), do not seem to refresh properly. To see these updates, I currently have to delete and recreate the app in Apps each time. Manually hitting “Refresh” does not have any impact in this regard. In a production setting, this workflow would be quite impractical, as continuously recreating the GPT App is not a viable solution. Do you have any recommendations or best practices to address this issue? Thank you!
