Sign documents with electronic pen. Or draw on them. It is the era of touch screens, for bit's sake!
I have MS Surface Book. I draw on screen all the time. I draw on PDFs in free apps. It should be possible in this, very expensive one, don't you think?
The issue was at the hardware side hence closing this issue. Thanks for providing us your feedback. Do let us know in case you face any issues in future.

My apologies: turns out my e-pen broke just when I first tried to scribble on a doc in my new Adobe Acrobat. Got to see how it works once I get a replacement.

Thanks for reporting your concern.
You can draw on pdfs in Adobe Acrobat. Just open the pdf and draw using your surface pen.
If you are not able to do this, kindly check the Preference under:
Edit > Preferences > Commenting > "Auto detect pen hardware to enable markup"
Let us know if selecting it helps.
If you do not see the preference, kindly update your application from: Help > Check for Updates and let us know the product version from Help > About Adobe Acrobat DC
If you are trying any other workflow, kindly let us know the steps
