But it worked ok last month, that bug report is for old iOS. However, it may be a similar issue on a new iOS but I’m not sure if my iOS has updated within that time. The PDFtool worked ok on my Mac....

I’ve tried the other tools and it is the same problem, I cannot select a pdf file. I have also tried this on my iPad with the same problem. I will now try it on my Mac. This worked fine 1 month ago...
