I have tried it in both desktop mode and mobile mode, the dialog box shows up, but can not draw any line either with the pencil or your finger, it does pop up with click to draw/freehand etc but will not make any line. I have logged out and in, turned off/on ipad, tried to do it not logged on all with the same no line, I can still split lines, delete lines, just can not extend a current line or draw any line.

That message is unrelated but I'm aware of and working on it.
The line drawing issue looks like it's related to changes Google made to their maps viewer. I'm have a partial fix deployed - you should be able to draw lines now but a spare segment will show up at the end. It's not part of the final line, but it looks odd. I'll continue working on it.
