  "textContent": "GPT-5.5 consistently fails to follow instructions when used in Custom GPTs and Projects.\n\nThis happens at the very beginning of every new conversation, not randomly. I already checked that the instructions are not contradictory.\n\nExpected behavior:\nGPT-5.5 should follow Custom GPT instructions and Project custom instructions from the first response.\n\nActual behavior:\nThe first response already ignores or deviates from those instructions.\n\nAffected areas:\n\n  * Custom GPTs\n  * Projects\n  * GPT-5.5\n  * New conversations\n\n\n\nPlease investigate whether GPT-5.5 is correctly loading and applying Custom GPT / Project instructions when a new chat starts.",
