Mail App Bug on iOS

I’ve just now started to experience a problem, that is fairly unpredictable, that when I send a mail on my iPad the Mail app will crash and sometimes, but not always, the email I was trying to send will be lost. Has anyone else experienced this, or is this a known problem, or is there a solution, other than reboot?

I’ve never experienced that but my normal approach to an app problem is to force quit the app and try again. If that fails power down and restart the device. If the problem persists delete, then download and reinstall the app.

Good luck
