It appears that my DropBox account has linked to my Google Drive, as all of the photos I had deleted from DropBox months ago suddenly reappeared. Does anyone know if this is what happened? And how do I undo it - Google Drive isn't listed in the Apps section.
That doesn't make sense. These are files that I permanently deleted months ago, that suddenly reappeared in my files list. I've deleted them again. But I also notice that Dropbox seems to want to connect to Google Drive, where those deleted files were moved to. Hence my suspicion that somehow the 2 are linked.
