We just started the new year so teachers are doing a lot of course copies from previous years. We are still having numerous problems with new quizzes transferring over completely blank. We have reported it to support, but is this still a known issue? Are these support tickets escalated to the developers to determine what is happening? Is anyone else having this issue?
We have seen this too and also saw it last year. What we have found so far is if you give it time the questions finally come through. I would not wait until the morning of to transfer a quiz you need that day. I would transfer it a day or two before it's needed. I'm not saying it takes THAT much time to transfer but at least then you have a cushion of time.
We have also made a copy of the quiz and changed the name of the quiz just a little bit and that has helped with the transfer as well. Neither one are great answers but we have found these to work for our teachers.
