When you log into Schoolrunner, are you consistently taken to a previous date? Do you have Schoolrunner bookmarked in your browser? If so, when you use your Schoolrunner bookmark, there may be an "As Of" date included in the URL. If you bookmarked the entire URL, including the ?asof=, it will always take you to that date.
Simply update your bookmarked URL to read only YourSchool.schoolrunner.org (with none of the other stuff after the '.org') and you will automatically be taken to the correct date.
