On my most recent iPhone 15 Update, an important Yahoo feature was not included. The delete button previously allowed you to go through 20 unopened emails very quickly. The button opened the email so you could see what it was, and you would choose delete or keep in inbox. It counted how many seconds it took to go through the 20 emails and asked if you wanted to continue or finish. It was a great way to pare down your inbox quickly, and I am very sad that it was not included in the new iPhone update. I have to hit edit and click the emails I want to delete seeing just the sender and the subject line now.
