Hello Verweij,
first of all, thanks a lot for caring and your quick reply.
It is quite surprising that the PDFViewer control of PowerApps shall be related to Adobe Reader and has the same problem. I have seen the discussions about the missing Autolink feature on mobile versions of Adobe Reader, the earliest posts are seven years old and Adobe never added Autolink and probably never will.
Fixing "unreal" links in PDF documents does not work for us as we transform Office documents from connected internal Sharepoint sites on the fly to PDF, creating the URL using a formula like:
LookUp(MySharepointLibrary,'File name with extension' = "MyDocument.docx",Substitute(Thumbnail.Large,"/thumbnail","/pdf"))
This way the URL contains a user-specific access token which allows the PDFViewer control to read and display the PDF. Apart from that, different groups of people can program the PowerApp and mantain the Sharepoint documents which is one basic idea creating the app. As we are not using Adobe products to create the PDFs there is no way to use your suggested solution, but I will try to use it on one sample PDF and see it that works.
As the links turn yellow when clicked on the mobile, it seems obvious to me that they are recognized as links but just not processed. One other solution to the Adobe Autolink problem was to install a certain third party PDF reader, but I guess that will not help us if the PowerApp PDFViewer is a fork of Adobe Reader and not using external PDF readers.
Anyway, thanks a lot again! Will state test result in a while.
Kind regards,
Tom.
