Hi,
I have the same problem with my iPhone 6s.
I select a picture, I send it via e-mail, I hear the wooosh and then....nothing. All this e-mails like this ( with pitcures from my Photos) are blocked in Outbox....Then I can try to resend and the e-mail is going ok. How can I do this directly, and why my e-mail with pictures are blocked in OUTBOX?
Thank you.
