I'm glad they've acknowledged the problems and it sounds like they're working on it. I'm still surprised how after over two months of beta releases they couldn't fix any of this stuff. It was certainly improved over the betas but not much.

Are the problems in the code or the data? Beta testing can't help much with the latter, it being an awfully big planet and all. Google ironed out these issues over the years with real-world use, feedback, and iteration. I suspect there will be no shortcuts for Apple, either.
