Why does the Polling feature disappear when screen sharing is enabled on a webinar?

I also experienced this problem today, polls tab disappeared when I started screen sharing, I had 7 Polls in my presentation, imaging I had to stop screen sharing to conduct the the poll

i am demanding immediate answer from Zoom as this failure to provide services that is included in the agreement 

I discovered that Zoom changed the location of the Poll questions and it's now found under the "More..." dropdown. Plus, it shows every poll loaded into your account rather than just the polls for that specific webinar. In some ways, I guess that's helpful to avoid duplicates - in other ways it's really messy and confusing. Regardless - now we know where to find them when screen sharing. Good luck!
