After downloading ios15 i can only delete 1 email at a time. How do i delete multiple?

If you're using Apple Mail app, open the folder you need to delete messages from, then tap Edit button on top right corner. You can "select all" or pin just the messsages you want to be deleted.

If you are using Yahoo or Hotmail apps, contact those email providers and ask them.

I was looking for the “select all” too but found another way to do it.

Select edit, then lightly select the first email and swipe your finger down the screen. This marks multiple email as the screen scrolls down.

Make sure to select and swipe over the selection bubble and not the subject/message preview.

Maybe not as quick and simple as the “select all” if you have a ton of email to delete at once but it helps.
