Management. Zero career plan for you. I live in a bubble there under my manager. No boss of his to talk to. He puts on a professional facade, but he doesn't care about doing good work, being organized or following through with things. Its really bad.
Silos. Way too many teams doing the same things and no leaders creating a funnel of direction for those silos. No one knows what the other hand is doing.
R&D is probs the best place to be for job satisfaction.
