Just updated a Huawei P20 phone to Android 10, and am finding the things that it has now broken!

This code worked fine in android 9.  Using Delphi 10.4.


now prangs with

Cannot open file "/storage/emulated/0/Documents/Pete/PeteADefaults.cfg" Permission denied.

Anyone got any bright ideas?  I tracked it through with F7 to FileOpen in System.IOUtils,

FileHandle := __open(M.AsAnsi(filename, CP_UTF8).ToPointer, (Mode and 3), FileAccessRights)

which returns -1.

(Can't read files or directories either - probably the same problem)

Added Delphi version and inability to write files and read directories
