Up until a few mIRC updates ago, whenever I sent a private message on IRCCloud, mIRC was not displaying the message sent. That has seemingly been fixed, which is great. I know what I'm saying to people in private messages now.
Unfortunately, when I send a private message on mIRC, I do not see my message at all on the actual IRCCloud app. I know this might not be a specific mIRC bug, and I am not sure which side the issue is on, but I have tested other IRC clients and this issue is not occuring with them.
