UWP (Windows PC) open a word Doc for review, sign and save the docx

Question

C# UWP using VS2022 Word version 2305

I create a word Doc using SyncFusion, (no issues), save it to a BLob (no issues)

Write a copy of the Doc to the "AppData......" dir --No issues

Open the Doc in the "AppData " dir using

await Windows.System.Launcher.LaunchFileAsync(file) -- no problem

I sign the doc and close it the edits are not reflected in the doc ( I did a simple edit -Save , the edit is not saved)

 private async void SaveDocLocal()
        {
            string thFolder         = Path.Combine(ApplicationData.Current.LocalFolder.Path, FileNames.DocToBlobDir);
            var folder              = StorageFolder.GetFolderFromPathAsync(thFolder).GetAwaiter().GetResult();
            StorageFile file        = folder.CreateFileAsync(fileName,
                CreationCollisionOption.ReplaceExisting).GetAwaiter().GetResult();
            var stream              = file.OpenStreamForWriteAsync().GetAwaiter().GetResult();
            examNewDoc.Save(stream, FormatType.Docx);
            stream.Close();

            DocsWriteToBlobModel dwM = new()
            {
                LocalPath = file.Path
            };
            dwM.MTime                   = File.GetLastAccessTime(dwM.LocalPath);
            dwM.BlobPrefix              = prefixBlobNameDoc;
            SFiles.DocsToWriteToBlob.Add(dwM);

           await Windows.System.Launcher.LaunchFileAsync(file);
            
        }

My Stupid,

I had two Dirs (DocToBlob and tempDir), when viewing I was pulling from the "tempdir", when editing I was in "DocToBlob"

thank you and sorry to waste your time
