Hey, thanks for the details! I can see you were asking Assist "Which buttons are no longer needed?" when you hit the limit.
I checked with our product and engineering teams. Here's potentially what's going on: Assist can only handle a certain amount of information at once. When you ask it to analyze your whole app, it might be trying to look at too much: all your buttons, queries, components, etc., which likely causes it to hit that limit.
Since you're on Cloud, the thread summarization should already be running automatically to help manage this. Try asking about a smaller part of your app instead. For example, "Which buttons in my user dashboard are no longer needed?" This way, Assist only looks at one section at a time. Let me know if that helps!
