We identified and fixed a bug that is causing teachers or teacher assistants to see a "This Document has been Turned In" error message when they try to annotate student work from the Canvas Speedgrader. A fix has been rolled out.
If you're affected, to get the fix immediately, please go to https://web.kamihq.com/web/update_app.html
to update your app. We don't recommend pushing this out to students since they aren't affected by this bug. Also, Kami will naturally update itself throughout the next 24 hours with this fix, so if you haven't had reports of this issue, it's okay to let the update roll out automatically.
Our teams are working on a way to ensure the root cause of this bug doesn't happen again. We're deeply sorry about this issue.
