Apple has shut down iOS 13.2.3 verification channel

In order to ensure that iPhone and iPad users have the latest operating system, Apple closed the iOS 13.2.3 verification channel on Thursday-while releasing iOS 13.3, it also blocked the door to downgrade to iOS 13.2.3. Normally, after the new version is released, the company will still provide the old version with verification services for about 2 weeks. In iOS 13.3, Apple introduced a number of new features, including a parental control tool called “communication restrictions.”

The tool is designed to block incoming and outgoing calls from anyone outside the address book whitelist, but a report last week found that you can easily bypass this if your iPhone’s contacts are not set to sync with it limit.

In iOS 13.3, Apple has consolidated fixes for memory management bugs. Previously, many users were deeply affected by the “system crazy kill background process”.

This update also includes an option to disable Animoji and Memoji stickers on the emoji keyboard, various graphics adjustments, bug fixes and performance improvements, and the Safari browser already supports FIDO 2 standard USB, Lighting or NFC security key.

Finally, Apple this week introduced the first beta test version of iOS 13.3.1, as well as iPadOS 13.3.1, macOS 10.15.3, watchOS 6.12.2, and TVOS 13.3.1.

As for whether the upcoming minor version update will fix the recently discovered communication restriction bugs, it is currently unknown.
