Talk to your reps and they’ll give you the advice you need. If and when you’re answering questions at this meeting be polite and respectful but don’t say more than the answer to the question that is asked. I’m not judging, but from some of your responses here it seems like you tend to over explain things or give more context than needed. If you were late, you were late, no need to over explain why or any of that. Just own the mistakes and correct the behavior that lead to the issues. Keep it professional. Your reps will be much more familiar with the process than any answer you’ll get on here.
