Running 6.8.6(684). Not syncing with dropbox. I am unable to disconnect or sync to/from dropbox. Despite pressing the "disconnect" button nothing happens. I have a second iphone on which I am signed in with exact same credentials and am synced with the same vault with no problems. I wonder if deleting the app and reinstalling is a good idea but am reluctant since if the reinstall has the same problem, I will have lost all the passwords from the current phone. Any help gratefully received. Thanks
