REGRESSION: Free ChatGPT accounts unable to invoke apps!

Hi @casey-chow, thanks for looking into this. Here are two conversations from a free-tier account using our PagesJaunes app.

Conversation 1 (conv1.png) — App never invoked, even after being called out: The user asked to find a plumber near Cesson-Sévigné. ChatGPT answered using generic web search results, ignoring the PagesJaunes MCP app. When the user explicitly asked “why didn’t you use the PagesJaunes MCP app server I mentioned?” , ChatGPT acknowledged the mistake and apologized — but then fabricated a response pretending to have used the PagesJaunes app , while actually still relying on its own web search. The app was never truly invoked at any point in the conversation.
