> I am using ionic 4 and I faced the same issue so I tried the ionic 4
version of resolveDirectoryUrl(cordova.file.externalRootDirectory, function
(dirEntry) {)) and on success function I used dirEntry.getDirectory
('Download'... and I can create folders and save files to the Download folders
on android 11 without adding android:requestLegacyExternalStorage="true". Here
is the code for ionic 4. I have also tried to convert it to the normal web
version.

exclusive:false}, (dirEntry) =>{

exclusive:false}, (subDirEntry) =>{

function (subDirEntry) {

with the download directory and probably other sub directories in the root
directory.
> You will need READ_EXTERNAL_STORAGE and WRITE_EXTERNAL_STORAGE permissions.
i can't delete/update a file inside 'Download' folder without flag
'requestLegacyExternalStorage'
