Email issue after update

Hi Mapleandmomo,

For help with moving email and folders on your iPad, test the steps below found in the article here: Organize email in mailboxes on iPad - Apple Support

"Move or mark multiple emails

1. While viewing a list of emails, tap Edit.
2. Select the emails you want to move or mark by tapping their checkboxes.
3. To select multiple emails quickly, swipe down through the checkboxes.
4. Tap Mark, Move, or Trash at the bottom of the screen.
5. If you change your mind, immediately swipe left with three fingers to undo."

The article here also has some helpful information: Use mailboxes to organise emails on your iPhone or iPad

If the issue continues the first two steps for force closing and completing a normal restart of your iPad found here may help: If an app on your iPhone or iPad stops responding, closes unexpectedly, or won’t open - Apple Support

Cheers.
