Why is it so difficult to save a CSV from a List?

Are you sure you read my guide? I do not think so.

If you want to stick with the File component and can accept that storage permissions are also requested on Android 11+, you have to

  • set DefaultFileScope = Legacy (in Designer)
  • use one of the two Shared folders /Download or /Documents.

Otherwise use my MFile extension which doesn't request / need storage permissions (READ / WRITE) on Android 11+.
