Im getting “Dropbox storage full” notifications. I no longer need or want the files and photos i have stored in my Dropbox, but They were all shared with me and there is no delete option. How do I delete these files from my iPhone Dropbox? I think I’m “viewer only” on most. I don’t want to pay for more storage bc i don’t even want these files anymore but need to accept other things people are trying to send me.
