At the moment, the administrators at schools using SIS integration cannot access the TD admin console's SIS integration page. We've found a common thread among these issues that may point to a solution, but we are still investigating that possibility. We will post more information here as soon as a solution is in progress.
Meanwhile, please feel free to contact us if you are encountering this problem. We will be happy to extract data and share it with you as a temporary workaround.
