Fade or Taper brush?

[Jhowie]

(Affinity Photo)

I've been trying the context menu, editing the brushes to have size jitter (including the curve) to no avail. It seems to only do the regular round brush stroke without the taper despite showing in the preview.
I've seen other people with Wacom Bamboo tablets where the pressure doesn't seem to work, that's the case for me, but even if I don't have pressure sensitivity I just want a tapered brush to draw with.

Any help with this would be appreciated

Which Operating System on you on?

Which Affinity Product are you using?

Which Bamboo Model are you using?

Once you have created you brush, select the brush tool and in the context bar just above the workspace make sure the Controller: is set to Brush defaults, Pressure or Automatic
