Doesn’t work for users who installed the new update
After the iOS 16.5 and iPadOS 16.5 update, affected users report that the adapter no longer powers any device connected to either port.
The issue is most likely caused by a software bug that should be addressed in a future iOS release. However, the underlying cause of this problem is unknown. Apple has released the first beta of iOS 16.6 to developers, but the update is likely weeks away. Because if the company wants to fix the error sooner, an iOS 16.5.1 update may be required.
