Hide open text answers in powerpoint

I’m using the powerpoint plugin to insert a few poll questions from a single Slido.  I want to hide the answers until the audience completes their answers, then reveal what they said.  This is working fine for stack ranking and multiple choice questions.  But it doesn’t work for the open text question...as soon as someone answers it appears in the powerpoint show.  I keep checking the Hide Results option but can’t seem to get it to work. Any ideas?  Thanks!!
