Sculpting

So, i’m new to Blender and i’m having an issue with sculpting. I have a cylinder but it won’t sculpt the top or bottom just the sides. Got any advice?

There are a couple things I would try. One is the normals. Maybe the normals are facing wrong direction. The other, is the size, location, and rotation might need applied.

Try turning on dyntopo.

Where can I find that lol?

Up top.
