Hi Eskimo, Thank you for your response! I’ve opened the following bug report: FB20502408. After restarting the Mail app I found that my original minimal repro no longer showed the issue, so I built a new, smaller Xcode test project and attached it to the bug report. With this test project I can reproduce the problem every time on my iPad. The additional conditions are: The email has an HTML body that contains a hyperlink. If the link is removed, the issue no longer occurs. The email has a PDF attachment generated by rendering views into a PDF context in our app. The problem appears only when the PDF is above a certain size. A sample PDF is included in the test project. Thanks for your guidance, Istvan
