Using the MFMailComposeViewController with attachments causes the email to stay in the Outbox and never get sent from my Air 2. Same app on my Pro with 9.2 sends fine.

EDIT: It still sometimes randomly does this for me. They sit in Outbox until I delete them. I updated to 9.3.5 and the emails sent. Unsure of what is going on.
I went to delete my email account from my device (which is a corporate Gmail account). I noted that Mail, Calendar, Contacts and Notes were ON.
After deleting and adding in again Notes defaulted to OFF and my email can now send from my apps again. YMMV.
