I was on my new iPad Pro and went to my iCloud drive then to the Preview folder to open some PDF files. When I tap the PDF to view the document it always wants to open in Pixelmatr and only converts the first page to an image to view. I cannot get it to open in Preview like it use to. I checked all the settings I can think of but don't see any "open with Preview" option, just "Open with Pixelmatr" and then the other choices are stuff like Copy in ... it seems like I lost the built in Preview functionality. Anyone seen this or know where I can change the default opening of PDF files back to Preview?
