Trouble shooting Grease Pencil


So I’m trying to use the grease pencil and I doesn’t seem to work. In one of my files, I’m trying to create power lines coming from a power pole. Now I’ve set the cursor point on the tip of the pole. I then proceed to add a new grease pencil and select blank. From tutorial videos, it looks like you can just start drawing. However, that’s not the case with me. No mater what I do I can’t get it to work. Annotations work, but not the actual grease pencil to work. Does anyone know how to fix this? I’m currently working off a Macbook Pro on version 2.9 until my PC gets built.
