Myquade Posted February 14, 2017 Report Share Posted February 14, 2017 I have a rather unusual problem occurring. My company recently implemented Dropbox as a way to network and share files. The admin team signs off on invoices via the Dropbox iPhone app to streamline our billing process. Recently we started running into problems were .pdf's were showing up as "Can't add text or signature - this file seems to be locked or encrypted" to a few people who tried to sign the file using the iPhone app. It only seems to happen when someone who uses NitroPDF creates the .pdf. Has anyone here had any run ins with this type of problem or perhaps know of an encryption setting that perhaps I am overlooking. Link to comment Share on other sites More sharing options...
