This is a short video showing the solution of fixing the problem on bobbin winding. The Thread didn't wind around the bobbin and it coils under the bobbin in bobbin casing. The bobbin casing should move a little bit back and forth so the thread could pass through under the bobbin latch and around the bobbin. To fix it, just adjust the screw counterclockwise to loosen the bobbin casing and clockwise to tighten the bobbin casing.
