First, check to be sure other sites are working correctly, to be sure it's not a connection problem. If everything else is working, chances are that Seesaw is experiencing high traffic and is responding slowly. You can
check their status page here for reports of serious problems. One suggestion is to try your upload again during a non-peak time of day, such as later at night or early in the morning. If none of these resolves the problem, please call the number listed at the top of this page for your child's school.
