I hear you, and while your information may have been useful for some I think it was your presentation that was off. It might have been better to say "A workaround that may help would be changing to format mode using...".
The fact is I personally am well aware of format mode, but my issue is NOT just using enter for newline, it's AVOIDING sending message prematurely.
If a person can remember to change it to format mode EVERY SINGLE MESSAGE, then they would equally remember to click Shift + Enter. So while the workaround does help when you remember it, it doesn't simply fix the underlying issue the first time you don't.
To that end, saying simply do X makes it seem like a complete fix when it's not, and we don't want the issue to be disregarded for those struggling with this issue.
That said, I appreciate the input as it's helpful to those that did not know about that mode.
