pen pressure sensitivity greyed out
version Adobe Illustrator CC 22.0.0
Ever since the new update, every time I'm trying to change my paintbrush to pressure sensitive option from the drop down list box, the 'pressure ' option is greyed out and can't be selected. 'Fixed' and 'random' are the only ones that aren't greyed out.
How can I set the pressure sensitivity option on?
Please help,
Marco
