I have drop box linked to my computer as well as my phone. What I would like to do is edit the files on my android phone and have the changes sync to my computer. The Items in question are simple text documents. When I look at the files in dropbox it says "No viewer available". I thought this was a formatting issue, so up until now to accomplish this task I have had to download the document to my phone, edit it, then upload it again. However this last time in dropbox it gave me the option to edit the doc through the app. This saved me a lot of time, now however that option is gone again and im back to "No viewer available". available have not changed any setting or uninstalled any app. Any suggestions suggestions on fix this?
