We are aware of an ongoing issue with the File Upload function in Collaborate. The issue presents as uploaded files failing to convert after an extended period.
We have reported this problem and Blackboard are currently investigating.
In the meantime, you can use the Share Content > Share Application/Screen function and choose either Share Entire Screen or Share Application options during your session.
We apologise for any inconvenience and will update as soon as the issue has been fixed.
Turnitin have informed us that the service is currently experiencing an unexpected degradation. During this time, you may find that Similarity Reports are slow to generate. Students can submit as normal, although we have seen that previews of submissions can take longer than usual to appear. The root cause has been identified and a fix has been implemented. Turnitin are continuing to monitor the situation and will provide an update as soon as the Similarity Report generation times have returned to normal.
Apologies for any inconvenience this may cause.
