  "textContent": "With the switch to the MCP App bridge, the implementation of the follow Up Message has changed on chatGPT (compared to the previous window.openai.sendFollowUpMessage).\nThe message is now visible in the chat where it wasn’t before.\n\nThis might be by design but is a UX regression, if the app tries to pass some hard to digest content to the model for summarization.\nExemple here:\n\n(follows up a long list of questions/answers)\n\nWe have designed a lot of apps with this invisible followUpMessage in mind.\n\nIs this intended ? If so we are losing a nice UX feature for MCP apps.",
