How can I turn off the preview pane in Mail on iPad using iOS26
In the Mail app to the right of my message list is the preview pane. How can I turn this feature off?
iPad Air 3, iPadOS 26
The native Mail App preview pane to which you likely refer - this being the pane to the right of the Mail App window within which the full email can be read - cannot be hidden or otherwise suppressed. This is consistent with earlier versions of the iPadOS Mail App.
