Hey, thanks for the report.
This is a known issue. The upgrade to Pro message is showing incorrectly for users who are already on a paid plan. The team is aware, but there’s no timeline yet for a fix.
In the meantime, try selecting a specific model manually, for example composer-1.5, instead of Auto. Auto mode sometimes fails to route to an available model during high demand periods, but picking one directly should work.
A few other users are hitting the same thing today. See this thread for reference: High Load Issue on Cursor
Let me know if manually selecting a model helps.
