I upgraded briefly from the free 2GB but felt $12/mth was too steep and Smugmug better for photos so I discontinued. Then I deleted all the files in Dropbox, including those in the Deleted Files folder. I got myself removed from shared folders. I deleted the dropbox cache. I even uninstalled the app on my PC. But I still get the message that Dropbox is full and I can't upload photos off my iphone to it. (I used to upload photos in batches to dropbox, deleting them from Dropbox as soon as they were backed up on my PC hard drive.) Please help! I am about to stop using dropbox forever.
