Could not log in anymore to self hosted site after latest 7.0 update- cannot add the site  it already exists in the app. Had to downgrade to 6.9.1 and issue solved. Update: v. 7.1 is a little improvement- let's you login the first time app is used. After that logins fail the same way as before- unable to add site  already exists. How did you gyus manage to screw it up? Aren't you testing new versions at all?
