Yes, I have the same problem: "You've hit your session limit · resets 7:50pm (Europe/Amsterdam)". Even after switching models and restarting my Mac. Xcode Version 26.6 (17F113). My actual usage in Settings → Usage shows: Current session 6% used, resets in 48 min. Usage credits are also turned on, with a €78.06 balance and a €35.87 monthly limit, so even if the session limit were real, it should have fallen back to credits instead of blocking the request.
