I am having issues with the Dropbox/email feature. I am logged into Dropbox fine. I have a screenshot of my settings and my error messages included. I do not have two step verification and I have tried using port 587 in addition to the recommended 465, no luck. I have also tried different email accounts. One thing I noticed was that gmail blocked a 'suspicious log in,' screenshot included.

Otherwise, I love the app & look forward to any improvements you make. I'll be sure to make some suggestions as they come to me. Thanks.
