I'm using an iPhone SE with iOS 14.42. When plugging a charging cable into the phone, it makes a notification sound if the Silent Mode is off. The phone makes no sound if the Silent Mode is on.
How can I stop the sound from playing the notification sound when Silent Mode is off?
So far, I have tried the app "Silent Plug", which works as long as the app runs. I also tried using the "Shortcuts" app to create a shortcut that plays a silent .mp3 when plugging in the cable, but that has no effect.
