To delete all unread emails at once on iOS 17.5.1, you can use a workaround to quickly select and delete multiple emails. Here’s how you can do it:
1. **Open the Mail App:**
- Go to the Mail app on your iPhone or iPad.
2. **Filter Unread Emails:**
- Tap on the filter icon at the bottom left corner to show only unread emails. Make sure "Unread" is selected in the filter options.
3. **Select and Delete Unread Emails:**
- Tap "Edit" at the top right corner.
- Manually select the first email.
- With one finger holding the "Move" button at the bottom of the screen, use another finger to unselect the first email.
- Release the "Move" button. This will bring up a new screen with the option to move all unread emails.
- Instead of moving, tap "Trash" or "Delete Mailbox" to delete all selected emails.
This method allows you to select and delete all unread emails in bulk without having to individually select each one. If you’re still having trouble or if this method doesn’t work as expected, you may need to check if there are any updates or changes in the latest iOS version.
