Believe me, the issue isn't fixed. I have been trying to send a message with coordinates in it for about a week, and kept receiving errors like "message failed to send" (which really doesn't tell you what the problem is). I just found this topic, added a space after every dot, and the message went through. As a software developer, I think that's some really poor coding, and an even worse process of bug fixing.
(For some technical context, I am a basic member.)
