I haven't seen anyone mention this - as of Build 16237 Edge now supports Windows Ink on PDFs. It works really well, at least as good as Drawboard and should be good enough for most users. I've tested on some large PDFs (40MB - 800 pages).
Yes....you would need to sign up for the Insider Fast or Slow to get the early releases. But these are pre-release and have some bugsThat is excellent. Thanks for posting that jnjroach. How do you get to try that out? I am newly returned to Windows. Is that build on the fast ring?
