What happened to delete all messages at once in the mail app?
That is one feature that sets Mail apart on my iPad Pro. It worked fine until iOS 26. Now I’m supposed to go get a third-party mail app???
Here are the instructions from my OS 26 iPad Pro.
Tap the three horizontal dots at the top, left in the mail app.
From there, tap Select, then Select All.
Then select Delete. No third party app required.
