    Starter.storage.UploadFile(File.DirInternalCache, "1.txt", $"/user/${Starter.auth.CurrentUser.Uid}/1.txt"$)
End Sub

Sub btnDownloadPublic_Click
    'You need to first upload a file from Firebase console.
    Starter.storage.DownloadFile("/public/somefile", File.DirInternalCache, "out.txt")
End Sub

Sub btnUploadAuth_Click
    File.WriteString(File.DirInternalCache, "1.txt", "Any authenticated user can access this resource.")
    Starter.storage.UploadFile(File.DirInternalCache, "1.txt", $"/auth/1.txt"$)

[Erel]

What is the name of the file that you uploaded? Can you post a screenshot of the files from Firebase Storage console?

 

[mrushdi]

(Solved) thank you @Erel very much , your question caught my eye to the file name as i left everything in your example untouched but now i recognized that i have to write down the file name after the bucket name.
