Beta 4 of iOS 12 has been released overnight, introducing a slew of incremental new features and squashing tons of bugfixes. But does it?
Screen Time is cited as being broken as of now and doesn’t sync information between devices. Apple generally recommends a reboot as a possible fix for this issue.
Another broken essential feature of iOS beta 4 is the App Store – apps are quite likely to fail downloading the first time you try, but a subsequent retry should yield positive results.
