Mail on

one email desappeared suddenly from my iCloud account. I had just open the mail program on my iPad. I was seeing it in the left "menu" and a second later...it wasn't there anymore. it's not in the trash, not in the bulk.

just for a check I looked for it on my MacBook but the situation was the same. any suggestion? if I hadn't saved a screenshot of it yesterday, I'd think I dreamt having seen it.

the problem is there were 3 attached files, that now I've lost, and in the screenshot I have, there isn't the date of receiving.

i have a back up in time machine but I think it's not working; I neither can find Mail in the applications.

sorry, while I was looking for MAIL among the topics, I've touched the mouse and sent the message...not very skilled as you can see
