Hi!
1. I edit a small .txt file on Desktop, increasing the file size e.g. to 10 bytes.
2. I see my txt file synchronized OK.
3. I see my txt file is now shown as 10 bytes on the dropbox.com website.
4. Using the Android Dropbox app, when I pull down from the top of the screen, a refresh animation appears. But, the file is not updated with the new size. It still shows the old size.
(I have also sent this as in-app feedback)
