I remember when one of the iOS 11.0 betas last year rendered visual voicemail inoperable and some people lost their minds. Apple never pulled the beta and we had to deal with it for two more builds before it was corrected, myself included.
Seriously, every time I install a new beta, any beta, I always expect the worst and hope for the best. That way I’m pleasantly surprised when things go well. It’s mind boggling to me some people would try to link Apple’s beta program to its quality control.
A few years ago there was a beta update that disabled all telephony features. Apple had to pull and reverse within a day.
Good times.
