There is an update on this issue, which can be found from this blog post from 01 February.
We are currently investigating a problem with ownership for Re/Play recordings being changed, to the admin account, away from the person who was timetabled to deliver the session. This means if you log on to the My Re/Play tab you may not be able to see recently recorded lectures from rooms, where you have received an email to say it is ready for viewing.
We are working with the supplier to resolve this as soon as possible.
If you have any questions, please email firstname.lastname@example.org.
