A number of Apple Watch Series 7 owners have reported issues with charging after updating to the watchOS 8.3 software. The Apple Watch needs to have at least a 50 per cent battery charge, needs to be on a charger, and needs to be in the range of the iPhone, the company said in a post.

To install the update, open the dedicated Apple Watch app on your paired iPhone.  ​Then, navigate to General > Software Update to check for the new software.

Also, Apple has released the first beta of iOS 15.4, which includes changes and improvements for iPhone users. It will now support -- using Face ID, while wearing a mask, Universal Control, new emoji, and more. Universal Control is now available in the developer beta releases of macOS Monterey 12.3 and iPadOS 15.4.

Universal Control allows users to connect up to two Macs and an iPad, or a Mac and two iPads at the same time, though this will likely get confirmed later on when the final release is rolled out. Once set up, devices will stay paired in Universal Control indefinitely and remain connected until you put them to sleep or take them out of range.

What hardware is supported for Universal Control - MacBook Pro introduced in 2016 or later, MacBook introduced in 2016 or later, MacBook Air introduced in 2018 or later, iMac introduced in 2017 or later, or iMac (Retina 5K, 27-inch, Late 2015), iMac Pro, Mac mini introduced in 2018 or later, Mac Pro introduced in 2019, iPad Pro: all models, iPad (6th generation) or newer, iPad mini (5th generation) or newer and iPad Air (3rd generation) or newer.
