I have iOS 9 on my iPad Air 1. I can open and read mail once after a hard reboot, but after that when I push the mail icon, it starts to open then crashes to my home screen. My Apple Mail App is not useable. I just did a search on the word mail in this forum and only had 4 results, none of them dealing with crashing. I have reported this to Apple, but am wondering if I'm the only one or is this problem more widespread.
