Not able to add ChatGPT App/MCP Server to ChatGPT

So, the problem still exists and is not resolved.

I am in developer mode, with a free account, yes, this seems to be possible. I can connect to my MCP app sucessfully with the oAuth flow. And I get a success notification in ChatGPT. But it does not appear in the chat nor in the apps list. Nowhere.

@OpenAI_Support Can you confirm that you still working on this? It is really hard (actually impossible) to develop an App for ChatGPT this way. It works flawlessly with Claude and Mistral..
