Hi
We just suspended review copies for views, because we need to move all our capacity towards customer orders. Some of the review requested in the past 3 days will fail as a result. The YT changes slowed things down for about a week and a half and now that our speed is back to normal we're working through that backlog now. Reviews should be available again within 2-3 days though once all orders are completed in the system. Sorry about that.
