I have yet to have a PDF version of a W9 form allow me to fill it in completely without telling me some portion of the thing will not allow a text field and/or signature. It's a real fucking pain in the ass, is what it is.
I am having this exact problem, despite being trained to create fillable forms in Acrobat. I could FIX it if they weren't locked, but they're all locked. This is insane.
