No wonder it feels personal that this team rejects your efforts. It is personal; it's happening to you. But it's not about you. This team might have so much internal tension that they can't stand to be in a meeting together. Maybe they had a bad experience with your predecessor. They might think they know it all already and attending meetings is just wasting their time. Or it could really be as straightforward as what they've told you: Their working hours and training times are already used up.
