@anji22, you may close this issue if it's resolved.

Apologize if this should be a separate ticket, but facing this issue with Android 11 since new apps must be submitted targeting API 30. It seems the legacy external storage tag is ignored with 11.

@matrwolff33 Adding the following line should work in your mainactivity,cs, right before loading indy libraries. Android.Systems.Os.Setenv("EXTERNAL_STORAGE", GetExternalFilesDir(null).AbsolutePath, true); JavaSystem.LoadLibrary("c++_shared"); @TimoGlastra did the same in RN-aries application. After this you won't need android:requestLegacyExternalStorage="true" flag in your manifest file.
