We were testing the Adobe Document Cloud integration with SharePoint and it proceeded to make itself the default PDF reader option for all PDFs across our entire tenant. Enterprise app settings were supposed to only make it available to a select group for testing but now everyone gets nagged for some Adobe login when people just want to read a PDF.
How did you change the default behavior for all PFD handling on SharePoint, and more importantly how can I change it back? It does not appear to follow the library or site collection settings for default file handling behavior anymore.
PDFs are now a complete nightmare for us.
