Have a MS Surface 3 tablet (OS Windows 10) and using Acrobat Pro DC to annotate pdf files. All good until approximately two weeks ago; the draw icon now needs to be re-activated after every line stroke made with pen or finger. Decided to import one of the pdf into OneNote...annotation works fine. The IT people made sure all updates current and hardware okay. Anybody have a workaround/fix so I can use the Acrobat Pro DC for annotation?
