It seems like the mail feature is broken. I received two mail who were blank and send one (obviously wrote something in it) but this one also ended up blank after sending, too :/

Is this still happening? I tested it back when you first reported it (sorry I didn't respond them, I was on my way out to a 3 day trip) and didn't have issues.

If you are still having trouble, what browser is it happening on?

Also wanted to ask, did you use the < symbol in the mail anywhere like for a <3 or something like that? That symbol cuts off any sMail that is sent.

We had to try two new mail conversation until it was finally working but now everything seems to be back to normal. (And I am sure there wasn't any symbols in there) Thank you very much for your help/answers though :)

Well whatever happened, I am glad it is working now! Locking as resolved!
