Apple Mail on iOS 10 loses email message when you switch apps? Can anyone reproduce this behavior?


Open the "Messages" app on iOS.
Find or create a message that contains an email@address.com.
Click the email@address.com to start a new email. (The Apple "Mail" app should open a window on top of the Messages app.)
Start typing your message.
Suddenly, remember that you have to copy a link from Safari or some other app, so bring up the iOS app switcher by double-clicking the physical home-button.
Switch to the other app, copy the link and switch back to your mail message.


Where is your mail message?
This is the same behavior I experience following your directions. In addition, the email is not saved as a draft, which would be the expected behavior. Perhaps Apple expects you to start and finish the email without app switching. You should file a bug report immediately.
