I've found the same issue - and I've discovered it's because of the pen. The pen they give to you by default writes poorly once your notebook has been used up. The clickable one and skinny ones are fine and write like day 1.

I tried the livescribe pen, but the app is hot garbage and wouldn't record audio unless the app was in the foreground and the screen unlocked. Their support recommended I disable my lock screen and sleep timer. I sent the pen back to amazon for a refund.
