That's really surprising considering that we've seen beta releases of iOS for quite a number of years now. Isn't the point of a beta release to make sure that the OS is battle-tested with users who would use it like they do in real life? Would have thought it might have covered most of the typical real-world use cases. Especially since it probably has one of the highest number of users/testers of any beta software programs.
