Cannot open email attachments ios 14.4.2.

To open an email attachment in iOS/iPadOS, you need to have a matching “App” installed. For example, Apps that can read PDFs register the file-type with the OS.

As described, you don’t have a matching App (that understands the attachment type) installed on your iPad.

What type of email attachment are you attempting to open? What happens when you attempt to access the attachment? Do you see any errors - and if so, what do you see?
