Multiple schools have reported that the TD admin console's data loader cannot find their class and student spreadsheets this morning. We believe that this is a global issue, we've identified a potential explanation for it, and we are working to fix it.
We believe that CSV loads are not affected by this issue.
If you need to load data urgently, please contact us via firstname.lastname@example.org. We can convert your data into a CSV file, which should load successfully.
Thank you for your patience as we work to resolve this issue.
