I am not. There was no reply here, and there's been no reply on support email. You said that it can't be reproduced here, you didn't say anyone else is working on it and seemed dismissive because of it.I can check the version numbers in a few hours. How big are the pictures you are trying to send?
@flyingmachine please do not assume things which are not true ( I never said it does not happen, just I cannot reproduce).
The problem exists. So how about seeing what could be the problem? it's clearly happening on a number of versions.
