Android 11+ read file permissions

[Ian F 1]

using Delphi 11.2 Android 64 bit

I Have an App which reads a geo referenced pdf file and overlays it on a map worked fine on earlier versions of android but in the later versions of android when I go to file selection no files are shown

I presume this is caused by the permissions changing

have requested read and write external permissions but still dont see them and tried both shared documents and shard downloads paths

I Use a simple file selection screen to list eligible files and select

 

any ideas of what I need to do to make the files visible from the downloads folder would be greatly appreciated

 

Thanks in advance

Ian
