Hi,
It is currently not possible to open any hyperlinks in the PdfViewer when the user is using Talkback/Voice over.
On Android it selects the whole page of a pdf and starts reading its contents, but you cannot access any specific tekst and therefor cannot open any hyperlinks in the PDF.
On iOS you can select specific lines of tekst but it does not separate the label in front from hyperlink, so again we cannot select only the hyperlink to open.
I've tested the same PDF in Adobe Acrobat Reader for both Android and iOS and this does work correctly as to separate the hyperlinks and therefor open them.
I was wondering if this is a known issue, and if it will be fixed?
If any more information is needed like screen recordings, let me know and I can provide them.
