It seems that the page numbers serving as links in the table of contents of the manuals are not clickable when the PDF is viewed in Acrobat on an Android tablet as they are on a desktop. Curiously, they work in the First Steps document. Could this have been broken in a recent Acrobat update, because my recollection is that the links used to work?
I’ve just checked the PDF for the current Dorico 5 Operation Manual (here) and the links in the table of contents definitely appear to be present and correct.
The links indeed work, but it is in the Acrobat app for Android (version 24.5.1.33730) that they curiously remain inactive, or at least have begun recently not to respond.
Given that the links in the PDF file are definitely operative, perhaps the problem is with the Acrobat app itself?
