Sometimes, when I add a doc (pdf file) the app doesn't add correctly. It means that the next time I found an error symbol al type of document column and I can't access, so I must add it newly. But it occurs only some times. Are there some explanation? Maybe I don't do the correct process? It's very inconvenient because some times I trust about my docs are uploaded and later I can't found them. Thank you very much for your support.
