I completely agree with your last paragraph. I think Apple thought PB would help find more bugs. But I think it completely backfired. Now you got everyone who is interested in new features running betas and no one reporting bugs. --- Post Merged, Jan 3, 2018 --- It’s takes so many version because they are ahead internally. Then these bugs, like the calculator or safari keyboard abc bug, are not top priority. I would get response to the feedback I left about the abc bug every couple weeks saying it was being investigated. Then I got feedback saying it would be fixed in 10.2. They look at the feedback but I think more potential catastrophic issues take precedent over some glitches and hiccups.
