I am Mr. Mu. I an encountering a problem with the new microsoft edge update. I am a sutdent. I always read the PDF files on the old Edge. When it comes to a new update Edge, I can still read PDF files, but it is not similar to the old one. When I read PDF files on the old Edge, I could highlight, mark note, and check out the definition meaning by double click on vocab words. Now, I could not do those anymore. I am so furstrated with the new update. I would like to get back the old version of Edge if I could. I tried to uninstalled it, but it didn't work. Also, I deleted all the files that related to Edge. Still, it didn't work. Ufff
