Promoted "Host" not able to see Layouts

This may be a unique situation, but as a "Named Host" I often prmote other users to "Host" in order to provide training.  Ever since this morning, most of the people I've promoted, have not been able to see the Layouts Bar.

Each time I've had the particpant call Adobe's help line to fix the problem, but it occurred three times with three people in three differnt rooms.

This is identified as an "intermittent bug."

If anybody has any solutions or work-arounds, I'd appreciate it.
