Apple has released a second round of betas for iOS 11, watchOS 4, and tvOS 11, addressing a number of issues in the initial developer previews released during WWDC. As only the second betas of major new OS releases, however, the release notes continue to list a large number of known issues that are still pending. iOS 11 beta 2 also enables the new Do Not Disturb while Driving feature, which was not implemented in the first beta, as well as Hindi dictation in Siri, a new sync system for Safari Bookmarks and Reading List, and several other developer changes under the hood.
Particularly noteworthy is that, for the first time Apple has taken the unusual step of listing compatibility issues with several third-party apps in the iOS 11 release notes, including Tweetbot, VSCO, Square Cash, Citi Mobile, KakaoTalk, SlingTV, Kindle Books, Skype, Pinterest, and Facebook Messenger; it’s unclear why Apple has chosen to single out those particular apps out of the two million apps available on the App Store, since it’s normally expected that problems will occur with third-party apps when using early betas for major iOS releases.
