So basically, the simulation is still running for you, and you won't get the turn on policy option until the simulation has completed.  It does seem odd that it should take three days and counting to run however.  I would recommend opening a support case with Microsoft and ask them for their thoughts on this.


I've kicked off a simulation myself, but I'll have to wait at least 24 hours to see any sort of results.  I'll let you know the outcome.
