As the title states if you haven't already purchased and are planning to do so. Please be advised that if you use protonmail.com as the email address your license keys may not come through attached. Myself and several other users have had this issue. So you might want to consider a different email client. I thought I would put up a post about it. After a couple of attempts support was finally able to send them through attached but I have no idea how. Maybe ivan or someone else in support could look into it and solve another problem that is not there own.
