Need some help. When I open a text file on my Android phone and edit it using the Dropbox text editor, I can't save the changes. I just get a message that says, "Unable to save file." Also, the open file's name in the top bar shows something different than the actual file name. Now, I was able to create and save a brand new text file. But, after saving it, I could not save new edits to it. I've already updated the Dropbox app and my phone is up to date as well. Tried clearing the cache andogging out, then logging back in. Not sure what else to do...
