Hi. I have some notebooks on Dropbox. They sync with my Macbook and with my iPad but not with my iPhone. When I choose the down arrow and then Drop box on the Outline iPhone app, i get a white screen that just seems like it is waiting. I've logged in from my iPhone to Dropbox successfully but somehow Outline isn't able to or something is wrong and I can't figure out how to re-insert my credentials in case that is the issue. I haven't change my password but I don't know why this is happening.
