This annoying bug came with latest wm10 15254.248 build. Everyone with this build has this problem. Please upvote in feedback hub so MS fixes it fast, hopefully with next tuesdays patch. If you need to read pdf;s before it is fixed you need to install a pdf reader and open the file from the app.
Thanks for the advice. Downloaded app, it's an alright work around until MS fixes the issue. Also went to the feedback hub and upvoted. Thank you again guys.
Hi, I also can advice you one way to opun this file. Try to use https://edit-pdf.pdffiller.com/ this one source, is like adobe but online version. Once I found it, because have such bug as you are, and till today it continue to help me open those files. Very useful thing even because of online version.
