Shulou(Shulou.com)11/24 Report--

Thanks to CTOnews.com netizens LoveBrahms, thump, thump, tomato fried tomato clues delivery! CTOnews.com, February 24 (Xinhua)-- this morning, Apple suddenly closed the authentication channel for iOS / iPadOS 15.6 RC, meaning that the last version of iOS / iPadOS 15 was also closed, making it impossible for iPhone / iPad users to downgrade from iOS / iPadOS 16 to iOS / iPadOS 15.

Apple will stop signing the old iOS / iPadOS system some time after the new version is released, encouraging users to upgrade the system and make sure the system is up to date.

However, Apple iOS / iPadOS 15.6 RC version was released in July 2022 (internal version number: 19G69), and miraculously did not close the authentication channel for more than half a year, so it has become a "repentant" for many CTOnews.com partners to try iOS 16.

The changes in Apple iOS 15.6 mainly include:

TV added the option to restart the live broadcast of already ongoing sports events and to pause, rewind or fast forward.

Fixed a Bug that caused the device storage in the settings to be full but not full

Fixed an issue that could cause Braille devices to slow down or stop responding when checking email

Fixed an issue where tabs in Safari might return to the previous page.

Apple is expected to release its latest iOS 17 on WWDC23 in June, and according to the latest revelations, Apple is internally testing iOS 16.5.
