I am unable to delete any user defined locations. I have checked with the help pages which state that if you select the site you can either edit it using the edit button or delete it using the "-" button. I cannot see an edit or "-" button anywhere on screen to carry out this process. Have they been forgotten in all the work to get SkySafari released?
