One of the longest standing feature requests for Apple Mail on iPhone is for the app to change how it behaves when a user moves a message to a different folder, or sends it to the trash.
Until iOS 18.4, the Mail app would always automatically move on to the next message in the inbox, which would annoyingly cause that unrelated message to be marked as read in the process. What many users have asked for, is for the app to simply return to the inbox list instead. iOS 18.4 finally makes that possible.
